[PATCH weston 11/13] compositor-drm: Cursors need to be broken with stereoscopy.

[Emmanuel Gil Peyrot]

From: Emmanuel Gil Peyrot <emmanuel.peyrot at collabora.com>

There is only one cursor plane per output, and we need to render two
cursors on stereo outputs, so currently set cursors_are_broken
globally.  In the future, this option could be changed to be per-output
to keep the plane optimisation for non-stereo outputs.
