This patch addresses some issues raised by the new and improved color handling. Basically the problem was that to init leaf object we needed access to a AQTColorMap from at init time. The fix is to defer setting of actual colors until the model is rendered for the first time. See renderInViewShouldRelease: in GPTRecieverObject.m where the model is sent an updateColors:(AQTColorMap *)map just before display.
With these changes AQT uses all of the new features and a property inspector could be added.
