Documentation
Z position is set up with drm_plane_create_zpos_immutable_property() and
drm_plane_create_zpos_property(). It controls the visibility of overlapping
planes. Without this property the primary plane is always below the cursor
plane, and ordering between all other planes is undefined. The positive
Z axis points towards the user, i.e. planes with lower Z position values
are underneath planes with higher Z position values. Two planes with the
same Z position value have undefined ordering. Note that the Z position
value can also be immutable, to inform userspace about the hard-coded
stacking of planes, see drm_plane_create_zpos_immutable_property(). If
any plane has a zpos property (either mutable or immutable), then all
planes shall have a zpos property.
