[PATCH 4/4] wined3d: Don't use depth textures without ARB_depth_texture.

[Stefan Dösinger]

This fixes bug 21708. There are still plenty of FBO bugs left in the
r200 driver though.

I assume the ARB_internalformat_query2 path does the right thing here,
but I cannot actually test it because the only GPU without
ARB_depth_texture that I have (r200) doesn't support
internalformat_query2.
