// FIXME another example of type switching. Cant put d2d code on other side of bridge in eg UGeometryBase abstraction
// and also, using a factory to create the UGeometryBase will make d2d specific versions.
// IDEA This is possible: Use factory (DI?) and check the Uxxx instances when passed to this type of class, and recreate
// a portion of the Uxxx if it doesnt match D2D? Factory could be configured for d2d/ogl etc. This links in with cacheing
// code too? Not sure if this will static compile :/ thats kinda the point... we'd need the Uxxx.ICreateStuff to be a specific
// D2D interface...could subclass... would check if(ICreateStuff is D2DCreator) as d2dcreator else Icreatestuff=new d2dcreator...
