[MESA PATCH] Fix nv40_miptree_layout pitch
...ed
textures. However, on my NV40 this causes a pgraph error regarding the
pitch register (and sometimes a system lockup too), which is fixed by
this patch.
I'm not sure how small mipmaps could have worked with the previous code.
Also the offset code below may need some review.
And furthermore, wide_pitch is set for any kind of texture usage, so
maybe it should be made unconditional (what's the point of allocating
a texture that the GPU can't use in any way?).
