Actually, what Tim meant on this occasion was a little joke.

Supporting different pixel formats (it's not just little vs big endian,
not by a long way) is a lot more than simply changing the bitmap layout;
there's quite large changes to the inner functioning of bitblt etc.
Fortunately, Andreas & I spent a couple of years arguing about this and
eventually FxBlt and the SurfacePlugin resulted. IIRC most of (even all
by now?) FxBlt has migrated into BitBlt over time and I really must get
around to trying to use it someday. It's on my list behind minor things
like trying to make enough money to keep eating, VI4 & VMbuild projects,
repairing half a dozen crunched model planes, making a boatload of
furniture etc etc.
