[igt-dev] [PATCH i-g-t] tests/kms_plane: Use solid colors for the cropping tests

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Something is wrong with the way we render stuff in the crop tests.
The renreded image can be different for different pixel formats,
at least when using fullscreen planes (maybe resolution dependent).
Go back to using just solid colors until someone figures out what's
wrong with the rendering.
