           Summary: Regression in wined3d introduces severe texture
                    artifacts

A regression in the implementation of wined3d causes a lot of 
rendering artifacts in certain games, for example the NekoPara series on 
steam.
Screenshot attached.

The offending commit is
1ddf2e47e252fd30976237bd190a98b310909301 wined3d: Use immutable storage for 2D 
textures.

After reverting that commit and it's child 
(4f9642d0e90b941e0316137523dbf12588c4bccc), it displays fine again.
Since I don't know too much about the 3d implementation, I'd be glad to have 
someone help me with that issue.

Tested on OpenSuse Tumbleweed (most recent), 32bit wine on 64bit OS.
