Robert Bragg d383bc0e61 remove internal use of cogl_texture_new_with_size
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.
