The new lightweight svg logo was not following text quite right.
The new `lookAt` method was not using the same logic the module was using internally on mouse movement.
I simply used that logic and exposed it via the old (expected) API, and got it behaving the way I like.
Fixed logo deallocation related bugs, had to patch the logo repo itself to add a stopAnimating method.
Also tuned up the logo to more closely resemble the old behavior.
- Overlaps the title text
- Points nose at cursor, not just front of eyes
- Cursor is more "distant" from fox, to avoid extreme angles on edges.
- No longer need to check for webGL compliance (svg rendered!)
- logo.canvas has been replaced with logo.container, since svg doesn't render to canvas but to an element.
Otherwise, worked with very little effort!!
