ad7969d9460b A client can now specify a global color key to be used with all images. The default color key is (255,0,255) in RGB format. Also the client can enable/disable the color key feature by using the setColorKeyEnabled function in the EngineSettings class. By default the color key feature is disabled. fixes[t:451]
