This moves the direct use of GL in cogl-framebuffer.c for handling cogl_framebuffer_read_pixels_into_bitmap() into driver/gl/cogl-framebuffer-gl.c and adds a ->framebuffer_read_pixels_into_bitmap vfunc to CoglDriverVtable. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 2f893054d6754e6bc7983f061b27c7858f1a593c)
