	set_values (GCValues *values, GCValuesMask values_mask) : none Sets attributes of a graphics context in bulk. Sets attributes of a graphics context in bulk. For each flag set in set as the new value for gc. If you're only setting a few values on gc, calling individual "setter" functions is likely more convenient.
