If there is a paint context available (i.e. for the phases that are during the actual stage paint), pass it along the callbacks, so that the callback implementations can change their operation depending on the paint context state. This also means we can get the current view from the paint context, instead of the temporarily used field in the instance struct. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1207
