Robert Mader	27dbf77d19	tests/wayland: Update documentation for MUTTER_REF_TEST_UPDATE ... For some reason `LIBGL_ALWAYS_SOFTWARE=1` does not work as intended while `MESA_LOADER_DRIVER_OVERRIDE=swrast` does.

Jonas Ådahl	d7ce6a47f8	tests: Add reference test framework ... This adds a test framework that makes it possible to compare the result of painting a view against a reference image. Test reference as PNG images are stored in src/tests/ref-tests/. Reference images needs to be created for testing to be able to succeed. Adding a test reference image is done using the `MUTTER_REF_TEST_UPDATE` environment variable. See meta-ref-test.c for details. The image comparison code is largely based on the reference image test framework in weston; see meta-ref-test.c for details.
