New shaders: * Fragment shader which writes depth sampled from a texture * Fragment shader which copies COLOR[0] to multiple render targets Additional improvements: * The fragment 'tex' shaders now take a sampler type (TGSI_TEXTURE_*) so that they can sample from any type of texture, not only from a 2D one.
