Subject: [PATCH] cursor-renderer/native: Add a means to disable HW cursors
When dealing with a faulty hardware or bugs in the driver, it might be
interesting to force the use of software cursors for debugging purposes.
Add a debug environment variable MUTTER_DEBUG_DISABLE_HW_CURSORS to
disable hardware cursors and force using software cursors.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/2046
