evas_render: Ensure proper rendering when objects are on planes

If only objects on planes change, we don't see any damage for the main
buffer, so a page flip never occurs and the plane doesn't update.  For
now forcing a tiny damage area is the easy way to work around this.

Also force a pixels get callback for enlightenment's surface frame
callback tracking.
