The 'cursor-mode', which currently is limited to RecordMonitor(), allows the user to either do screen casts where the cursor is hidden, embedded in the framebuffer, or sent as PipeWire stream metadata. The latter allows the user to get cursor updates sent, including the cursor sprite, without requiring a stage paint each frame. Currently this is done by using the cursor sprite texture, and either reading directly from, or drawing to an offscreen framebuffer which is read from instead, in case the texture is scaled. https://gitlab.gnome.org/GNOME/mutter/merge_requests/357
