tile-preview: Remove non-composited case

Browse Source 
The main reason for handling the non-composited case was to keep
code differences with metacity small, but the tiling patch[0] never
got merged. In mutter itself, the compositor is not optional, so
there's no good reason for keeping those untested code chunks around.
