[PATCH 0/1] MR10653: gdiplus: Assume bitmaps are top-down in image-reading code.

[Esme Povirk (＠madewokherd)]

Noticed when looking at https://bugs.winehq.org/show_bug.cgi?id=40409, but I don't think this noticeably improves performance. Still, it cuts down on some extra work and simplifies the code.
