Leap Motion inputs' context

[Goutte]

Hi !

I pulled the latest Jax (the shader awesomeness), and I found out a bug that's puzzling me : this now references window in my controller's leap_hand_translated method, instead of the controller itself.

I don't know if you're aware of this, the branch being a work in progress ; I don't know how to fix it (besides monkey-patching my controller by re-assigning this), or I would have ;).

As a side note, I had no occasion to delve into the new shaders, so I cannot provide constructive feedback except that I trust you entirely on this matter. 🐹

Note that this has the expected value when I'm using => to define the method, as in :

class AwesomeController extends Jax.Controller
  leap_hand_translated: (e) =>
    console.log this

(which is pretty much the same as re-assigning this, but hey, it works !)
