Yes, I believe it has been supported since 4.1.4. It's at least included in
4.2

It would be very easy. You would have to implement color conversion from RGB32
and add this to the blit() function of QScreen (or, preferably, a subclass).

It shouldn't be much of a difference, if any. Both will touch equal amounts of
memory (read 4 bytes and write 3 bytes per pixel).
