- /* David Steele comented :
-
- Some things to bear in mind:
-
- We currently keep a copy of the mix color in the ColorVisual object, which is then used to instantiate the registered property on the renderer.
-
- The user can get the renderer and animate the mixColor property (it's registered, so is automatically a scene-graph property).
-
- The GetProperty method will have to read from the renderer, or from the cached value in the Visual, and the SetProperty will have to write to cache and to the renderer if present.
