Jonas Ådahl 0ec335395d screen-cast: Add 'cursor-mode' to allow decoupled cursor updates
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.
