Currently, `meta_frame_get_mask()` and `meta_ui_frame_get_mask()` will return the frame mask applied to the current frame size, by querying the frame themselves. To be able to get the frame mask at an arbitrary size, change the API to take a rectangle representing the size at which the frame mask should be rendered. https://gitlab.gnome.org/GNOME/mutter/merge_requests/1009
