[PATCH 0/1] MR521: ddraw: Don't account video memory for sysmem surfaces' draw textures.

[Stefan Dösinger (＠stefan)]

Star Trek Starfleet Academy does not like it when available video memory
goes down after creating a system memory resource. It destroys all its
textures and recreates them, and in some sitations forgets to recreate
one or another texture, resulting in rendering bugs.

I suspect the game is trying to detect focus loss by monitoring for
unexpected video memory changes.

I am open to renaming WINED3DUSAGE_PRIVATE to something else, like
WINED3DUSAGE_NO_VIDMEM_ACCOUNTING. This particular name is ugly long
though.
