Believe me when I say that avoiding image list is one of the best things
that you can possibly do! We have a large image list and have some serious
problems with certain video cards and their drivers where the transparent
images are dran non-transparently, partially, not at all, or the wrong
image is drawn.
Most of the S3-Trio, Intel i810 video and some earily ATI Rage cards have
drivers that just don't handle masked blits correctly over a certain
point. At this stage I'm on the verge of writing my own careful minimal
transparent blit operation for image list type bitmaps just so that we can
avoid all the damn support calls about the pink backgrounds and having to
explain why the video driver bugs are not our problem. Sigh.
Cheers, Max.
