-/** We always use per-vertex colors so that rects can be batched across color changes. Sometimes we
-    have explicit local coords and sometimes not. We *could* always provide explicit local coords
-    and just duplicate the positions when the caller hasn't provided a local coord rect, but we
-    haven't seen a use case which frequently switches between local rect and no local rect draws.
-
-    The color param is used to determine whether the opaque hint can be set on the draw state.
-    The caller must populate the vertex colors itself.
-
-    The vertex attrib order is always pos, color, [local coords].
