Code Activity

New internal class CachedComponentImage, which is used internally to manage component buffering. I've used this to rebuild the OpenGLComponent's rendering algorithm so that it now supports sub-components and can have 2D content drawn in its paint method. Updated the openGL demo to show this in action.
