[mutter] tests: Test non-native monitor transform

[Jonas Ådahl <jadahl src gnome org>]

commit 52af529950d4262b6cd576b923aae08f2d2774f7
Author: Jonas Ådahl <jadahl gmail com>
Date:   Tue Mar 21 17:28:45 2017 +0800

    tests: Test non-native monitor transform
    
    Test that configuration works as expected when the backend doesn't
    support handling the transform and an intermediate offscreen
    framebuffer is used.
