I'm really confused now. Has it not been case all along? Component 
ordering would affect all 32-bpp bitmaps, regardless of them having a 
useful alpha channel or not...

If you are using a 32-bpp overlay, then bmp_color_depth(screen) == 32, no?

You know, I think this is all a big misunderstanding and that we are 
really arguing about two different things...
