sprite op• 数据种类:无 → rgba(仅由参数决定的算子 —— 不接受图像或数据输入)
• 调用:import gfx2d; gfx2d.sprite_synthesize(kind='disc', size=32, color='emphasis', thickness=0.25, scheme='okabe_ito')(或 opsgfx2d.get("sprite_synthesize"))
确定性的抗锯齿测试精灵 `rgba (size, size, 4)`。

The entry point of the sprite sort: it needs no asset on disk, and because
the silhouette comes from an implicit equation the alpha channel *is* the
ground-truth coverage mask — which is the whole reason this family belongs
in a vision library.
`kind is "disc", "ring", "box", "diamond" or "star"`.
`color is a :mod:palette` role name (default) or an explicit 3/4-tuple.
`thickness` is the ring's wall as a fraction of the radius.
Coverage is computed by 4x4 regular supersampling, so alpha takes values on
the exact lattice `k/16`.
