Just pass it in to the vertex shader like in GLES, it's one less thing to vary between drivers. mutter is, shall we say, not a heavy user of point primitives, so any performance impact (it might be measurable, who knows) is not an issue. Again, the feature flag remains to be cleaned up in a future commit. https://gitlab.gnome.org/GNOME/mutter/merge_requests/995
