Robert Bragg fa5a9c88fe atlas-texture: remove some use of _COGL_GET_CONTEXT
This removes several uses of _COGL_GET_CONTEXT in cogl-atlas-texture.c.
Notably this involved making CoglPangoGlyphCache track an associated
CoglContext pointer which cogl-pango can pass to
_cogl_atlas_texture_new_with_size().
