The previous code to initialise the depth state on the default pipeline wasn't initialising the magic number. If you later tried to retrieve the depth state using cogl_pipeline_get_depth_state you would end up with an invalid depth state struct and you would just get warnings if you tried to use it for anything. This patch just replaces the initialisation with a call to cogl_depth_state_init because it uses the same values anyway. Reviewed-by: Robert Bragg <robert@linux.intel.com>
