GeometryUsage enum
What a buffer will be bound as.
Not a hint. One backend cannot infer it and cannot change its mind:
WebGL binds a buffer to its target for life, so a buffer uploaded as
vertices can never afterwards be bound as indices — the attempt is an
INVALID_OPERATION, the draw is dropped, and the frame comes back the clear
colour with nothing logged anywhere.
flutter_gpu has no such split: a DeviceBuffer is untyped and a
BufferView binds either way, which is why the contract went without this
until a second backend was written against it. The engine has always known
which it was uploading, so saying so costs a word at each call site.
