This adds COGL_PIXEL_FORMAT_RG_88 and COGL_TEXTURE_COMPONENTS_RG in order to support two-component textures. The RG components for a texture is only supported if COGL_FEATURE_ID_TEXTURE_RG is advertised. This is only available on GL 3, GL 2 with the GL_ARB_texture_rg extension or GLES with the GL_EXT_texture_rg extension. The RG pixel format is always supported for images because Cogl can easily do the conversion if an application uses this format to upload to a texture with a different format. If an application tries to create an RG texture when the feature isn't supported then it will raise an error when the texture is allocated. https://bugzilla.gnome.org/show_bug.cgi?id=712830 Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 568677ab3bcb62ababad1623be0d6b9b117d0a26) Conflicts: cogl/cogl-bitmap-packing.h cogl/cogl-types.h cogl/driver/gl/gl/cogl-driver-gl.c tests/conform/test-read-texture-formats.c tests/conform/test-write-texture-formats.c
