In preparation for removing the automagic cogl-auto-texture apis this adds a more minimal version of the cogl_texture_new_with_size code to cogl-atlas.c for creating textures used to migrate images out of an atlas and to cogl-texture-pixmap-x11.c. Note: It turned out that both of these minimal versions were the same so I did consider keeping a shared utility, but since the implementations are very small and potentially due to the differing requirements for atlas and pixmap-x11 textures we might even want them to differ later I chose to keep them separate. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6d64307483713e7a5a7ef554275619def51b840f) Conflicts: cogl/cogl-atlas.c cogl/winsys/cogl-texture-pixmap-x11.c
