I think the only question is whether SetSolidConsts() should support
2101010 formats. I believe solid pictures are always a8r8g8b8, so it
shouldn't matter in practice. But that function already supports all other
formats, so maybe the 2101010 ones should be added for the sake of
consistency.

But either way:
