the mesh ID for a full update. The conditions it uses are troublesome: 1. There must be an evaluated mesh 2. The evaluated mesh's active byte color layer must equal the original's This logic doesn't make sense for a few reasons. First of all, the `mloopcol` pointer doesn't make sense in the context of color attributes (rather than the old vertex colors), since it only points to byte color attribute on face corners. Second, just because the layer pointers are equal doesn't mean something doesn't depend on the attribute's values. I think the best solution currently is to remove this "fast update" case and instead work on optimizing the general case. Also, T95842 suggests removing these pointers, and this is one of the last remaining uses of `Mesh.mloopcol`. Differential Revision: https://developer.blender.org/D15275
