Currently implemented switching from yuv to rgb, looking up rgb from the table in the usual way, getting back to yuv. With luma lookup presets (sepia, heat, xray) a color space conversion is saved directly looking up rgb for a given Y and converting to yuv. Probably this latter step can even be made faster precalculating a luma to yuv table in an outer loop. https://bugzilla.gnome.org/show_bug.cgi?id=625817
