UiGeometry

Remarks

⚠ Thirty-two-bit indices, and not because a frame is expected to need them. Almost none do: sixteen bits reach 65 535 vertices, which is sixteen thousand quads, and a dense editor window is a few thousand. The reason is what happens to the one frame that does — an index that wraps draws geometry from the top of the frame in the middle of it, silently, and the picture is wrong rather than absent. Emitting the wider index costs two bytes per index on about an eighth of the frame's bytes, and buys never having to reason about the ceiling again.
