The fire effect will be contain within width = 10 and 200\n    low_ & high_ values must be in range [0 ... width_]  \n        \n    * FIRE HEIGHT:\n    \n    input factor_ : float\n    \n    The fire maximum height can be adjust with the variable factor_ (float value)\n    value > 3.95 will contain the effect within the display \n    value < 3.95 will enlarge the effect over the display height  \n    Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually \n    to contain the fire effect within the display\n        \n    * SPEED CONSIDERATION\n    \n    input reduce_factor_ : integer\n    \n    The argument reduce_factor_ control the size of the texture to be processed \n    e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)\n    Smaller texture improve the overall performances but will slightly degrade the fire aspect, \n    especially if the blur and smooth option are not enabled.\n    Recommended value for reduce_factor_ is 3 (fast process)   \n    reduce_factor_ values must be an integer in range [ 0 ... 4] \n    The reduce_factor_ value will have a significant impact on the fire effect maximum height, \n    adjust the argument factor_ accordingly\n\n    * FIRE INTENSITY AT THE SOURCE\n    \n    input fire_intensity_: integer\n    \n    Set the fire intensity with the variable fire_intensity_, 0 low flame,\n    32 maximum flame effect\n    Values must be an ""int in range [0 ... 32] \n\n    * SMOOTHING THE EFFECT\n    \n    input smooth_: True | False\n    \n    When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear \n    filtering) or False the final texture will be adjust with the scale function.\n    Set this variable to False if you need the best performance for the effect or if you require\n    a pixelated fire effect. Otherwise set the variable to True for a more realistic effect. \n\n    \n    * BLOOM EFFECT \n    \n    input bloom_         : True | False\n    input fast_bloom_    : True | False\n    input bpf_threshold_ : integer\n       \n    Fire effect produce a bright and smooth light effect to the background texture where the fire \n    intensity is at its maximum.\n    Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances\n    The flag fast_bloom_ define a very fast bloom algo using only the smallest texture \n    to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect \n    project for more details.\n    When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will \n    produce a more realistic fire effect (this will slightly degrade the overall performances). \n    If the fire effect is too bright, you can always adjust the bright pass filter value\n    bpf_threshold_(this will adjust the bloom intensity)\n    bpf_threshold_ value must be in range [ 0 ... 255]   \n    Below 128 the bloom effect will be more noticeable and above 128 only the brightest\n    area will be enhanced.\n\n    * LIGHT EFFECT INTENSITY\n\n    input brightness_            : True | False\n    input brightness_intensity_  : float\n\n    When the flag is set to True, the algorithm will use an external function, \n    <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture\n    A custom color can be passed to the function defining the pixels to be ignored during t""he \n    process (default is black color).\n    the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness \n    of the flame effect and positive values will increase the brightness of the effect (causing\n    bright white patches on the fire texture). \n    Values below -0.4 will cause the fire effect to be translucent and this effect can also be \n    used for simulating ascending heat convection effects on a background texture.\n    \n    \n    * OPTIONAL SURFACE\n      \n    input surface_ : pygame.Surface\n      \n    This is an optional surface that can be passed to the shader to improve the performances \n    and to avoid a new surface to be generated every iterations. The surface size must match \n    exactly the reduce texture dimensions otherwise an exception will be raise. \n    see reduce_factor_ option to determine the fire texture size that will be processed.\n    \n    * COLOR PALETTE ADJUSTMENT  \n    \n    input adjust_palette_ : True | False\n    input hsl_            : (10, 80, 1.8)\n\n    Set this flag to True to modify the color palette of the fire texture. \n    This allow the HSL color model to be apply to the palette values\n    You can redefine the palette when the flag is True and by customizing a tuple of 3 float \n    values, default is (10, 80, 1.8). \n    The first value control the palette hue value, the second is for the saturation and last, \n    the palette color lightness. \n    With the variable hsl_ you can rotate the palette colors and define a new flame\n    aspect/color/intensity\n    If adjust_palette_ is True the original palette define by the argument palette_, will \n    be disregarded.Instead a new palette will be created with the hsl values\n\n    * FLAME ORIENTATION / DIRECTION & BORDER FLAME EFFECT\n     \n    input transpose_ = True | False,\n    input border_    = True | False,\n    \n    transpose_ = True, this will transpose the final array \n    for e.g :  \n    If the final fire tex""ture is (w, h) after setting the transpose flag, the final \n    fire texture will become (h, w). As a result the fire effect will be transversal (starting \n    from the right of the display to the left side). \n    You can always transpose / flip the texture to get the right flame orientation  \n    BORDER FLAME EFFECT \n    border_ = True to create a flame effect burning the edge of the display. This version is only\n    compatible with symmetrical display or textures (same width & height). If the display \n    is asymmetric, the final border fire effect will be shown within the display and not neccessary \n    on the frame border \n    \n    * FINAL TOUCH\n    \n    input blur_ : True | False\n    \n    This will will blur the fire effect for a more realistic appearance, remove all the jagged \n    edge when and pixelated effect\n    \n    \n    :param width_           : integer; Size (width) of the surface or display in pixels\n    :param height_          : integer; size (height) of the surface or display in pixels\n    :param factor_          : float; Value controlling the fire height value\n                              must be in range [3.95 ... 4.2].\n                              The value 3.95 gives the highest flame effect\n    :param palette_         : numpy.ndarray, buffer containing mapped RGB colors (uint values)\n    :param fire_            : numpy.ndarray shape (w, h) containing float values (fire intensity).\n                              For better performance it is advised to set the array to the size \n                              of the texture after applying the reduction_factor_.\n                              For example if the reduction_factor_ is 2, the texture would have \n                              width >> 1 and height >> 1 and the fire_array should be set to \n                              numpy.empty((height >> 1, width >> 1), float32)\n    :param reduce_factor_   : unsigned short int ; Can be either 0, 1, 2, 3, 4. \n            ""                  2 and 3 provide the best performance and the best looking effect.\n    :param fire_intensity_  : Integer; Control the original amount of energy at the\n                              bottom of the fire, must be in range of [0 ... 32]. \n                              32 being the maximum value and the maximum fire intensity\n    :param smooth_          : boolean; True smoothscale (bi-linear filtering) or\n                              scale algorithm jagged edges (mush faster)\n    :param bloom_           : boolean; True or False, True apply a bloom effect to the fire effect\n    :param fast_bloom_      : boolean; Fastest bloom.

 1523:     
 1524:     input width_  : integer,  
 1525:     input height_ : integer
 1526:     
 1527:     width_ and height_ values define the size of the texture e.g Surface(width x height)
 1528: 
 1529:     * FIRE ASPECT (CONTROL OVER THE WIDTH): 
 1530:     
 1531:     inputs low_ : integer  
 1532:     input high_ : integer 
 1533:     
 1534:     Optional arguments low_ & high_ (integer values) define the width 's limits of the fire effect. 
 1535:     low_ for the starting point and high_ for the ending of the effect.
 1536:     e.g low_ = 10 and high_ = 200. The fire effect will be contain within width = 10 and 200
 1537:     low_ & high_ values must be in range [0 ... width_]  
 1538:         
 1539:     * FIRE HEIGHT:
 1540:     
 1541:     input factor_ : float
 1542:     
 1543:     The fire maximum height can be adjust with the variable factor_ (float value)
 1544:     value > 3.95 will contain the effect within the display 
 1545:     value < 3.95 will enlarge the effect over the display height  
 1546:     Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually 
 1547:     to contain the fire effect within the display
 1548:         
 1549:     * SPEED CONSIDERATION
 1550:     
 1551:     input reduce_factor_ : integer
 1552:     
 1553:     The argument reduce_factor_ control the size of the texture to be processed 
 1554:     e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)
 1555:     Smaller texture improve the overall performances but will slightly degrade the fire aspect, 
 1556:     especially if the blur and smooth option are not enabled.
 1557:     Recommended value for reduce_factor_ is 3 (fast process)   
 1558:     reduce_factor_ values must be an integer in range [ 0 ... 4] 
 1559:     The reduce_factor_ value will have a significant impact on the fire effect maximum height, 
 1560:     adjust the argument factor_ accordingly
 1561: 
 1562:     * FIRE INTENSITY AT THE SOURCE
 1563:     
 1564:     input fire_intensity_: integer
 1565:     
 1566:     Set the fire intensity with the variable fire_intensity_, 0 low flame,
 1567:     32 maximum flame effect
 1568:     Values must be an int in range [0 ... 32] 
 1569: 
 1570:     * SMOOTHING THE EFFECT
 1571:     
 1572:     input smooth_: True | False
 1573:     
 1574:     When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear 
 1575:     filtering) or False the final texture will be adjust with the scale function.
 1576:     Set this variable to False if you need the best performance for the effect or if you require
 1577:     a pixelated fire effect. Otherwise set the variable to True for a more realistic effect. 
 1578: 
 1579:     
 1580:     * BLOOM EFFECT 
 1581:     
 1582:     input bloom_         : True | False
 1583:     input fast_bloom_    : True | False
 1584:     input bpf_threshold_ : integer
 1585:        
 1586:     Fire effect produce a bright and smooth light effect to the background texture where the fire 
 1587:     intensity is at its maximum.
 1588:     Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances
 1589:     The flag fast_bloom_ define a very fast bloom algo using only the smallest texture 
 1590:     to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect 
 1591:     project for more details.
 1592:     When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will 
 1593:     produce a more realistic fire effect (this will slightly degrade the overall performances). 
 1594:     If the fire effect is too bright, you can always adjust the bright pass filter value
 1595:     bpf_threshold_(this will adjust the bloom intensity)
 1596:     bpf_threshold_ value must be in range [ 0 ... 255]   
 1597:     Below 128 the bloom effect will be more noticeable and above 128 only the brightest
 1598:     area will be enhanced.
 1599: 
 1600:     * LIGHT EFFECT INTENSITY
 1601: 
 1602:     input brightness_            : True | False
 1603:     input brightness_intensity_  : float
 1604: 
 1605:     When the flag is set to True, the algorithm will use an external function, 
 1606:     <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture
 1607:     A custom color can be passed to the function defining the pixels to be ignored during the 
 1608:     process (default is black color).
 1609:     the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness 
 1610:     of the flame effect and positive values will increase the brightness of the effect (causing
 1611:     bright white patches on the fire texture). 
 1612:     Values below -0.4 will cause the fire effect to be translucent and this effect can also be 
 1613:     used for simulating ascending heat convection effects on a background texture.
 1614:     
 1615:     
 1616:     * OPTIONAL SURFACE
 1617:       
 1618:     input surface_ : pygame.Surface
 1619:       
 1620:     This is an optional surface that can be passed to the shader to improve the performances 
 1621:     and to avoid a new surface to be generated every iterations. The surface size must match 
 1622:     exactly the reduce texture dimensions otherwise an exception will be raise. 
 1623:     see reduce_factor_ option to determine the fire texture size that will be processed.
 1624:     
 1625:     * COLOR PALETTE ADJUSTMENT  
 1626:     
 1627:     input adjust_palette_ : True | False
 1628:     input hsl_            : (10, 80, 1.8)
 1629: 
 1630:     Set this flag to True to modify the color palette of the fire texture. 
 1631:     This allow the HSL color model to be apply to the palette values
 1632:     You can redefine the palette when the flag is True and by customizing a tuple of 3 float 
 1633:     values, default is (10, 80, 1.8). 
 1634:     The first value control the palette hue value, the second is for the saturation and last, 
 1635:     the palette color lightness. 
 1636:     With the variable hsl_ you can rotate the palette colors and define a new flame
 1637:     aspect/color/intensity
 1638:     If adjust_palette_ is True the original palette define by the argument palette_, will 
 1639:     be disregarded.Instead a new palette will be created with the hsl values
 1640: 
 1641:     * FLAME ORIENTATION / DIRECTION & BORDER FLAME EFFECT
 1642:      
 1643:     input transpose_ = True | False,
 1644:     input border_    = True | False,
 1645:     
 1646:     transpose_ = True, this will transpose the final array 
 1647:     for e.g :  
 1648:     If the final fire texture is (w, h) after setting the transpose flag, the final 
 1649:     fire texture will become (h, w). As a result the fire effect will be transversal (starting 
 1650:     from the right of the display to the left side). 
 1651:     You can always transpose / flip the texture to get the right flame orientation  
 1652:     BORDER FLAME EFFECT 
 1653:     border_ = True to create a flame effect burning the edge of the display. This version is only
 1654:     compatible with symmetrical display or textures (same width & height). If the display 
 1655:     is asymmetric, the final border fire effect will be shown within the display and not neccessary 
 1656:     on the frame border 
 1657:     
 1658:     * FINAL TOUCH
 1659:     
 1660:     input blur_ : True | False
 1661:     
 1662:     This will will blur the fire effect for a more realistic appearance, remove all the jagged 
 1663:     edge when and pixelated effect

 1673:                               For better performance it is advised to set the array to the size 
 1674:                               of the texture after applying the reduction_factor_.
 1675:                               For example if the reduction_factor_ is 2, the texture would have 
 1676:                               width >> 1 and height >> 1 and the fire_array should be set to

 1782:     
 1783:     The cloud maximum height can be adjust with the variable factor_ (float value)
 1784:     value > 3.95 will contain the effect within the display 
 1785:     value < 3.95 will enlarge the effect over the display height  
 1786:     Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually 
 1787:     to contain the cloud effect within the display

 1793:     The argument reduce_factor_ control the size of the texture to be processed 
 1794:     e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)
 1795:     Smaller texture improve the overall performances but will slightly degrade the cloud aspect, 
 1796:     especially if the blur and smooth option are not enabled.
 1797:     Recommended value for reduce_factor_ is 3 (fast process)   
 1798:     reduce_factor_ values must be an integer in range [ 0 ... 4] 
 1799:     The reduce_factor_ value will have a significant impact on the cloud effect maximum height,

 1814:     When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear 
 1815:     filtering) or False the final texture will be adjust with the scale function.
 1816:     Set this variable to False if you need the best performance for the effect or if you require
 1817:     a pixelated cloud effect. Otherwise set the variable to True for a more realistic effect. 
 1818:    
 1819:     * BLOOM EFFECT

 1825:     Bloom effect produce a bright and smooth light effect to the background texture where the cloud 
 1826:     intensity is at its maximum.
 1827:     Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances
 1828:     The flag fast_bloom_ define a very fast bloom algo using only the smallest texture 
 1829:     to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect 
 1830:     project for more details.
 1831:     When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will 
 1832:     produce a more realistic cloud effect (this will slightly degrade the overall performances). 
 1833:     If the cloud effect is too bright, you can always adjust the bright pass filter value
 1834:     bpf_threshold_(this will adjust the bloom intensity)
 1835:     bpf_threshold_ value must be in range [ 0 ... 255]

 1845:     <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture
 1846:     A custom color can be passed to the function defining the pixels to be ignored during the 
 1847:     process (default is black color).
 1848:     the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness 
 1849:     of the cloud effect and positive values will increase the brightness of the effect (causing
 1850:     bright white patches on the cloud texture). 
 1851:     Values below -0.4 will cause the cloud effect to be translucent 
 1852:     
 1853:     
 1854:     * OPTIONAL SURFACE
 1855:

 1857:       
 1858:     This is an optional surface that can be passed to the shader to improve the performances 
 1859:     and to avoid a new surface to be generated every iterations. The surface size must match 
 1860:     exactly the reduce texture dimensions otherwise an exception will be raise. 
 1861:     see reduce_factor_ option to determine the cloud texture size that will be processed.

 1870:     If the final cloud texture is (w, h) after setting the transpose flag, the final 
 1871:     cloud texture will become (h, w). As a result the cloud effect will be transversal (starting 
 1872:     from the right of the display to the left side). 
 1873:     You can always transpose / flip the texture to get the right cloud orientation  
 1874:

 1876:     
 1877:     input blur_ : True | False

 1892:                                   array to the size of the texture after applying the 
 1893:                                   reduction_factor_. For example if the reduction_factor_ is 2, 
 1894:                                   the texture would have to be width >> 1 and height >> 1 and the 
 1895:                                   cloud_ array should be equivalent to numpy.empty((height >> 1,

 2018:     
 2019:     Choose a lens texture from the Assets directory (free textures provided in Assets directory 
 2020:     of this project). All textures are sizes 5184x3456 and would have to be re-sized to  
 2021:     your game display and used by function `dirt_lens`. 
 2022:     The function dirt_lens will not resize the texture for you.
 2023:     
 2024:     The setting light_ is a float values cap between -1.0 to 0.2 and allow you to increase the 
 2025:     light source oriented toward the camera. Values <0.0 will decrease the lens dirt 
 2026:     effect and values >0.0 will increase the brightness of the display and increase the 
 2027:     amount of dirt on the camera lens (your display).
 2028:     
 2029:     Optionally the setting flag_ can be changed from BLEND_RGB_ADD to any other pygame optional 
 2030:     flags value. BLEND_RGB_ADD is the default setting and allow the pixels from the dirt lens 
 2031:     texture to be blended (added) to the display and provide the brightest and better looking 
 2032:     effect. 
 2033:     
 2034:     This effect can be used for real time rendering for surfaces resolution 1024x768

 5483:     THIS SHADER CREATE A WATER EFFECT ON A PYGAME SURFACE
 5484:     This version does not include any background deformation to keep a reasonable fps rate
 5485: 
 5486:     * GLOBAL VARIABLE CONSIDERATION
 5487:     Set 3 arrays as global numpy arrays (not in the main loop, these arrays does not have
 5488:     to be created every frames).
 5489: 
 5490:     current = numpy.zeros((width, height), dtype=numpy.float32)
 5491:     previous = numpy.zeros((width, height), dtype=numpy.float32)
 5492:     array = numpy.full((width, height, 3), 0, numpy.uint8)
 5493: 
 5494:     * ADD A WATER DROP
 5495:     To add a water drop to the display just add an integer value to the array previous such as
 5496:     previous[random.randint(0, width - 1), random.randint(0, height - 1)] = 1024
 5497:     with width and height matching the size of the array (width, height = previous.get_size())
 5498: 
 5499:     * PROCESSING TIME
 5500:     Then update the transformation. The function below will start the blurring process
 5501:     (flattening the
 5502:     values across the array to absorb the drop energy ; 1024 in the example above.
 5503:     Finally the arrays are swapped : current become previous and previous become current
 5504:     Note that:
 5505:     1) w & h must match the array size
 5506:     2) previous & current & array must be identical sizes otherwise an error will be thrown
 5507: 
 5508:     previous, current, array = shader_ripple_c(w, h, previous, current, array)
 5509: 
 5510:     * CREATING THE SURFACE
 5511:     The array is then transformed into a numpy.ndarray of type uint8 (unsigned char 0..255)
 5512:     The pygame make_surface method will convert the array type (w, h, 3) into a surface that can
 5513:     be blit to the active display.
 5514:     surf = make_surface(asarray(array, dtype=uint8))
 5515: 
 5516:     * BLIT
 5517: 
 5518:     The newly surface containing the drops can then be added to the current background or
 5519:     display (blit process).
 5520:     Both surface should have the same size for a more realistic effect
 5521:     The special_flag here is BLEND_RGBA_ADD but can be set to a different value to achieve the
 5522:     special effect needed (BLEND_RGB_MULT, BLEND_RGB_SUB) etc.
 5523:     Refer to blending modes to understand the math operation behind the flags
 5524: 
 5525:     surface_.blit(surf, (0, 0), special_flags=pygame.BLEND_RGBA_ADD)
 5526: 
 5527:     * BOOSTING THE FPS
 5528:     In order to boost the processing time, I downscale the surface prior processing and
 5529:     upscale it x2 when
 5530:     the process is done, this method provide an additional overall performance.

 6708:     input height_ : integer
 6709:     
 6710:     width_ and height_ values define the size of the texture e.g Surface(width x height)
 6711: 
 6712:     * FIRE ASPECT (CONTROL OVER THE WIDTH): 
 6713:     
 6714:     inputs low_ : integer  
 6715:     input high_ : integer 
 6716:     
 6717:     Optional arguments low_ & high_ (integer values) define the width 's limits of the fire effect. 
 6718:     low_ for the starting point and high_ for the ending of the effect.
 6719:     e.g low_ = 10 and high_ = 200. The fire effect will be contain within width = 10 and 200
 6720:     low_ & high_ values must be in range [0 ... width_]  
 6721:         
 6722:     * FIRE HEIGHT:
 6723:     
 6724:     input factor_ : float
 6725:     
 6726:     The fire maximum height can be adjust with the variable factor_ (float value)
 6727:     value > 3.95 will contain the effect within the display 
 6728:     value < 3.95 will enlarge the effect over the display height  
 6729:     Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually 
 6730:     to contain the fire effect within the display
 6731:         
 6732:     * SPEED CONSIDERATION
 6733:     
 6734:     input reduce_factor_ : integer
 6735:     
 6736:     The argument reduce_factor_ control the size of the texture to be processed 
 6737:     e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)
 6738:     Smaller texture improve the overall performances but will slightly degrade the fire aspect, 
 6739:     especially if the blur and smooth option are not enabled.
 6740:     Recommended value for reduce_factor_ is 3 (fast process)   
 6741:     reduce_factor_ values must be an integer in range [ 0 ... 4] 
 6742:     The reduce_factor_ value will have a significant impact on the fire effect maximum height, 
 6743:     adjust the argument factor_ accordingly
 6744: 
 6745:     * FIRE INTENSITY AT THE SOURCE
 6746:     
 6747:     input fire_intensity_: integer
 6748:     
 6749:     Set the fire intensity with the variable fire_intensity_, 0 low flame,
 6750:     32 maximum flame effect
 6751:     Values must be an int in range [0 ... 32] 
 6752: 
 6753:     * SMOOTHING THE EFFECT
 6754:     
 6755:     input smooth_: True | False
 6756:     
 6757:     When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear 
 6758:     filtering) or False the final texture will be adjust with the scale function.
 6759:     Set this variable to False if you need the best performance for the effect or if you require
 6760:     a pixelated fire effect. Otherwise set the variable to True for a more realistic effect. 
 6761: 
 6762:     
 6763:     * BLOOM EFFECT 
 6764:     
 6765:     input bloom_         : True | False
 6766:     input fast_bloom_    : True | False
 6767:     input bpf_threshold_ : integer
 6768:        
 6769:     Fire effect produce a bright and smooth light effect to the background texture where the fire 
 6770:     intensity is at its maximum.
 6771:     Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances
 6772:     The flag fast_bloom_ define a very fast bloom algo using only the smallest texture 
 6773:     to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect 
 6774:     project for more details.
 6775:     When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will 
 6776:     produce a more realistic fire effect (this will slightly degrade the overall performances). 
 6777:     If the fire effect is too bright, you can always adjust the bright pass filter value
 6778:     bpf_threshold_(this will adjust the bloom intensity)
 6779:     bpf_threshold_ value must be in range [ 0 ... 255]   
 6780:     Below 128 the bloom effect will be more noticeable and above 128 only the brightest
 6781:     area will be enhanced.
 6782: 
 6783:     * LIGHT EFFECT INTENSITY
 6784: 
 6785:     input brightness_            : True | False
 6786:     input brightness_intensity_  : float
 6787: 
 6788:     When the flag is set to True, the algorithm will use an external function, 
 6789:     <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture
 6790:     A custom color can be passed to the function defining the pixels to be ignored during the 
 6791:     process (default is black color).
 6792:     the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness 
 6793:     of the flame effect and positive values will increase the brightness of the effect (causing
 6794:     bright white patches on the fire texture). 
 6795:     Values below -0.4 will cause the fire effect to be translucent and this effect can also be 
 6796:     used for simulating ascending heat convection effects on a background texture.
 6797:     
 6798:     
 6799:     * OPTIONAL SURFACE
 6800:       
 6801:     input surface_ : pygame.Surface
 6802:       
 6803:     This is an optional surface that can be passed to the shader to improve the performances 
 6804:     and to avoid a new surface to be generated every iterations. The surface size must match 
 6805:     exactly the reduce texture dimensions otherwise an exception will be raise. 
 6806:     see reduce_factor_ option to determine the fire texture size that will be processed.
 6807:     
 6808:     * COLOR PALETTE ADJUSTMENT  
 6809:     
 6810:     input adjust_palette_ : True | False
 6811:     input hsl_            : (10, 80, 1.8)
 6812: 
 6813:     Set this flag to True to modify the color palette of the fire texture. 
 6814:     This allow the HSL color model to be apply to the palette values
 6815:     You can redefine the palette when the flag is True and by customizing a tuple of 3 float 
 6816:     values, default is (10, 80, 1.8). 
 6817:     The first value control the palette hue value, the second is for the saturation and last, 
 6818:     the palette color lightness. 
 6819:     With the variable hsl_ you can rotate the palette colors and define a new flame
 6820:     aspect/color/intensity
 6821: 
 6822:     * FLAME ORIENTATION / DIRECTION & BORDER FLAME EFFECT
 6823:      
 6824:     input transpose_ = True | False,
 6825:     input border_    = True | False,
 6826:     
 6827:     transpose_ = True, this will transpose the final array 
 6828:     for e.g :  
 6829:     If the final fire texture is (w, h) after setting the transpose flag, the final 
 6830:     fire texture will become (h, w). As a result the fire effect will be transversal (starting 
 6831:     from the right of the display to the left side). 
 6832:     You can always transpose / flip the texture to get the right flame orientation

 7177:     Smaller texture improve the overall performances but will slightly degrade the cloud aspect, 
 7178:     especially if the blur and smooth option are not enabled.
 7179:     Recommended value for reduce_factor_ is 3 (fast process)   
 7180:     reduce_factor_ values must be an integer in range [ 0 ... 4]

 7212:     project for more details.
 7213:     When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will 
 7214:     produce a more realistic cloud effect (this will slightly degrade the overall performances).

 7230:     the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness 
 7231:     of the cloud effect and positive values will increase the brightness of the effect (causing
 7232:     bright white patches on the cloud texture).
