[Marvin Fröhlich]

I have replaced the old resource cache system, that never worked and was never really used with a new robust system, that automatically frees OpenGL resources when a SceneGraph object is being GCed or when the Canvas is being destroyed. Do don't have to do anything manually except for the case, if you store objects in a local cache and don't have them (or a shared copy) in the scenegraph. In this case you have to manually call the freeOpenGLResources() method, before destroying the Canvas. This method is defined on any Node and NodeComponent and automatically traverses the sub-graph. The ResourceBag also has this method. So if you're using the ResourceBag as your local cache, you can simply call this method on the ResourceBag and everything is fine.

These news allow you for recreation of the Canvas for resolution changes etc. at runtime. There is absolutely no problem with limited canvasIDs anymore. You should be able to recreate the canvas any number of times. Separate Canvases should be no problem, too. But this is a rare case and should anyway not be done in favor of multiple viewports on one canvas.
