No, simply that one might expect a 32-bit RGBA sprite to be an enhanced 32-bit
RGB sprite, so that every drawing operation which works for the latter works
for the former as well, in particular the plain draw_sprite.

I mean that, if a 32-bit RGBA format was supported by the hardware, its layout
would highly likely match that of the 32-bit RGB format. Therefore we would
have to use the 32-bit RGB order of the card for our 32-bit RGBA format in
order to benefit from hardware-acceleration.
