Subject: GL_(UN)PACK_SKIP_IMAGES should only be applied to 3D texture pack/unpacking
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=60909388ab136d849d99eab49e782a53772a618f;p=mesa.git

GL_(UN)PACK_SKIP_IMAGES should only be applied to 3D texture pack/unpacking
and ignored for 1D and 2D images.
Need to pass in image dimensions (1,2,3) to the _mesa_image_address() function.
This change gets propogated to some other routines.
Also added new _mesa_image_address[123]d() convenience functions.
