mutter/src/backends/native/meta-cursor-renderer-native.c
Hans de Goede da600b8400 cursor-renderer-native: Take panel-orientation into account for sprite transform 
When calculating the transform we should apply to the cursor sprite
before uploading it to the cursor plane, we must also take into
account non upright mounted LCD panels.

Otherwise the cursor ends up 90 degrees rotated on devices where the
LCD panel is mounted 90 degrees rotated in its enclosure.

This commit fixes this by calling meta_monitor_logical_to_crtc_transform
in get_common_crtc_sprite_transform_for_logical_monitors to adjust the
transform for each Monitor in the LogicalMonitor.

Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1123

/* When animating a cursor, we usually call drmModeSetCursor2 once per frame.
* Though, testing shows that we need to triple buffer the cursor buffer in
* order to avoid glitches when animating the cursor, at least when running on
* Intel. The reason for this might be (but is not confirmed to be) due to
* the user space gbm_bo cache, making us reuse and overwrite the kernel side
* buffer content before it was scanned out. To avoid this, we keep a user space
* reference to each buffer we set until at least one frame after it was drawn.
* In effect, this means we three active cursor gbm_bo's: one that that just has
* been set, one that was previously set and may or may not have been scanned
* out, and one pending that will be replaced if the cursor sprite changes.
