Avoid slow drawing of bitmaps with alpha in wxAUI (PR #25983)
VZ
See #23841.
If no problems are found with this, it should be backported to 3.2 by just adding 24 to the code creating the bitmap (i.e. without the first commit here).

marekr left a comment (wxWidgets/wxWidgets#25983)So far the individual that experienced the slowdowns the heaviest reports it seems to be fixed with this patch applied to our 3.2 based builds. Letting it sit awhile longer since it wasn't always the most consistently reproduced issue

vadz left a comment (wxWidgets/wxWidgets#25983)I'm going to merge this, as I'd like to backport it to 3.2 too, but any feedback would still be welcome, of course!
