Animating a canvas element returned from an ImageryProvider?

I see that an imagery provider can return a tile as a canvas element. I haven't tried yet, but can I keep writing (animating stuff) to the canvas tile once it's returned?


Currently, the image or canvas returned by an imagery provider is immediately uploaded to the graphics card as a texture, and is not updated afterwards. Eventually, this is likely to change, in order to allow things like rendering videos directly onto terrain.
