Fix for the mipmap problem

Hi,

Since the tiling changes in the r300g driver I have observed problems with non
square textures in some mipmap levels. I have not nailed the problem down to a
specific level or a specific texture size, but the attached patch looks
plausible to me and fixes some fallout I observed since these patches with my
favourite OpenSceneGraph test model displayed in osgviewer.

Please review/apply.

Mathias
