libweston: assert when transforming for views with dirty transforms
If the view transform is dirty it might be incorrect. Also, we normally set up the view transform matrix properly regardless of whether the transform is enabled or not - but if we've never run weston_view_update_transform() it will be all zeros. This is a step towards removing view->transform.enabled checks and just using the transform matrix in all cases. Signed-off-by: Derek Foreman <derek.foreman@collabora.com>
