[PATCH 0/1] MR4513: opengl32: Add a FIXME when doing a mapped buffer copy.

[Aida Jonikienė (＠DodoGTA)]

I should've pushed this shortly after the workaround for the WineD3D
WoW64 graphics corruption got upstreamed (which I discovered when
messing around) but never got around to MR anything in Wine.

The copies of mapped buffers introduce significant performance overhead
(I'll add a FIXME so that people don't get surprised when their old games
run like a slideshow like for example NFS Most Wanted).
