It works correctly with scanouts, in contrast to clutter_stage_capture_into. Inspired by meta_screen_cast_area_stream_src_record_to_buffer. maybe_paint_cursor_sprite is now unused and thus removed. v2: * clutter_stage_paint_to_buffer requires switching to recording from an idle callback as well. (Jonas Ådahl) v3: * Set human readable name for idle source. (Ivan Molodetskikh) Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1940 Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1914>
