auxiliary: support using PIPE_TEXTURE_RECT internally
Currently Gallium internals always use PIPE_TEXTURE_2D and normalized
coordinates to access textures.
However, PIPE_TEXTURE_2D is not always supported for NPOT textures,
and PIPE_TEXTURE_RECT requires unnormalized coordinates.
Hence, this change adds support for both kinds of normalization.
