GrVertexColor stores either kind of color, and GrVertexWriter does the
right thing. SkColor4fPrepForDst helps to automate the conversion and
pinning. This ensures that colors are already pinned if the device has
no support for half-floats. This way, ops never need to worry about caps,
they can just check if all colors they're batching are normalized.
