	* clutter/cogl/gles/cogl-texture.c: 	(cogl_texture_download_from_gl:) Implemented a workaround 	for missing alpha framebuffer channel. There are still 	some issues with detecting whether alpha is present in the 	framebuffer. See comments in code. Test-cogl-tex-getset now 	successfully retrieves a RGBA texture image data.
