There was a lot of redundancy in how we tracked the width and height of different texture types which is greatly simplified by adding width and height members to CoglTexture directly and removing the get_width and get_height vfuncs from CoglTextureVtable Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 3236e47723e4287d5e0023f29083521aeffc75dd)
