An improved version if cliptest is at:
http://cgit.collabora.com/git/user/pq/wayland-demos.git/log/?h=cliptest

New features: keyboard controls and proper use of
weston_surface::transform.enabled, see
http://cgit.collabora.com/git/user/pq/wayland-demos.git/tree/clients/cliptest.c?h=cliptest#n24

The surface orientation dot is now bright, when the surface is not
transformed.


Thanks,
