BTW, I've just moved away from using PNG's for AU graphic objects and
now use WIN BMP's with pre-calculated alpha (again
cross-platform reasons).
The difference in re-draw speed is amazing (thanks to the
pre-calculation). If anyone needs any hints on this then I'd be glad
to help -
definitely worth the extra effort.

I am curious (having worked quite a lot on drawing optimisations of
layered bitmaps for AUGUIFramework...). What BMP can do that PNG can't
?
Ben, were you saying that your BMPs are totally solid (non transparent)?
I think the speedup must be due to not having to composite images at
all--just bliting on top of the buffer. Using BMP format itself
probably doesn't matter.
