Add ability to animate unsynced models

Currently we can only draw binding poses, but there's no way to tie up the animation scripts nor API to draw it.

Start by locating the existing code for drawing binding poses and the animation scripts or API mentioned in the issue. Determine how unsynced models are represented and what interfaces would need to be connected. Done means unsynced models can be animated through the engine's supported scripts or API.
