piglit/texwrap is a good texturing test. By default, it covers filtering,
wrapping, texture border color, and texture swizzling with the selected
texture format. It can optionally test NPOT dimensions, projective
texturing, and the deprecated one-pixel border. You can choose from 1D, 2D,
3D, and RECT texture targets. It doesn't test mipmapping though.
