First round of chages to add zoom to the camera with zero impact to the game SDK code. I have wired the node up to listen to actions, and added the filters that seem reasonable to suppress those actions. Although there is a scalar for how far to zoom the camera, it is not yet incorporated into the code that positions the camera.
The camera zoom now works as a scalar for the camera offset vec3 giving us a working zoom feature, albeit very simple.
