libweston: Don't request repaint in output enable
Allow for the compositor to start without first displaying a blank screen when no startup transition is used. This patch is under review in the mainline weston repository. It should be useable for other use cases besides drm-lease, but right now this patch causes the weston test suite to fail by unconvering an unrelated problem with wayland event handling[1]. For now, keep this with the drm-lease support under agl-devel until the weston test suite issue is resolved and the patch is merged upstream.

+Subject: [PATCH] compositor: do not request repaint in output_enable
+
+When enabling a weston_output, the compositor damages the entire output,
+to ensure that the entire output is redrawn. However, this triggers a
+repaint, which might happen before anything is actually drawn. The
+result is a black frame before the shell is displayed.
+
+Damage the entire output region, but do not trigger the repaint when
+enabling a weston_output.
+
