test-utils: Expose the compare_pixel function
The compare pixel function was a static function used internally by the test_utils_check_* functions. It takes a pointer to a pixel in a buffer read back from Cogl and compares it with an expected value. This function could also be useful in tests wanting to check the data returned from a call to cogl_texture_get_data so we should share it with the rest of the tests. https://bugzilla.gnome.org/show_bug.cgi?id=668913 Reviewed-by: Robert Bragg <robert@linux.intel.com>
