Y'all want to see a cool shader?

This is mashing up two ideas:

- @iquilezles@twitter.com's closed-form "signed distance to a quadratic Bézier curve" solver
- using winding number to determine inside/outside-ness

Putting these two ideas together, we can render a Bézier font from its raw control points, as a single (huge) closed-form math expression!
