This is a regression since wine-3.0 where I last saw it working. Photoshop
panels render to pitch black but can still be interacted with.

Confirmed broken in wine/stable (4.0) and wine/master (currently tag:wine-4.2)

I did a git bisect from wine-3.0 (good) to wine-3.10 (bad) and landed on these
two commits. The last one I could not tag as it causes Photoshop to crash.

gdi32: Build the region object directly instead of making a copy in
CreatePolyPolygonRgn.

gdi32: Pre-allocate the points array in CreatePolyPolygonRgn.
