[Bug 35205] WOLF RPG Editor 2.10: Updating the whole texture in IDirect3DDevice9::UpdateTexture() breaks font caches

--- Comment #10 from Matteo Bruni  ---
You probably want to store a struct wined3d_box instead and in general handle
dirty areas for 3D textures too (the latter can be a separate patch I guess).
There is still the question about how multiple dirty areas are supposed to be
handled and if the existing tests aren't affected by your patch, we clearly
need more tests.

I'd start by extending the test, adding some interesting cases and running it
on Windows. The testbot might help somewhat but you really want to test on
actual Windows boxes with real GPUs.
