I've decided to go down that path. The added conversion functions
aren't big, it remains pretty clean and in fact it allows me to
neatly separate the functions between BE and LE framebuffers instead
of "swap" and "non-swap" which avoids one of the macro tricks I had
to do before.
Additionally, we are missing some pixel formats in some of the UIs
for my extended cases of surface sharing so I'll work on that too.
(I wonder if we should add a UI callback to verify if a pixel format
is supports for sharing ... for now I'll just add all the missing
ones to SDL 1 & 2, but somebody will have to look at spice).
Cheers,
Ben.
