[compiz] [PATCH] Always use mipmaps in cube plugin

[Bartosz Taudul]

Currently, the cube plugin uses mipmapping only when cube is unfolded.
When the cube is rotated, mipmaps are not used, which leads to ugly look
of textures.

The attached patch fixes this. This leads to another kind of artifacts,
which are fixable with anisotropic filtering.

The leftmost image is the current state of cube plugin. The center image
is with mipmaps enabled. The rightmost is with mipmaps and anisotropic
filtering.
