fillText produces odd results with some fonts about node-pureimage HOT 7 OPEN

I'm looking at this again. Even with C command support (Bézier curves) it still looks wrong. Looking at the path stream it seems that a TTF creates one long path where as the OTF creates three paths. I see three Z commands (end of path) in the OTF stream and just one in the TTF stream. This explains why the centers are filled. The TTF has a single path so the inside/outside polygon test works correctly. The OTF is essentially drawing three separate polygons: the outside shape of the B, then the first hole, then the second hole. Of course the code doesn't know that these second ones should be holes instead of additional polygons. I'll have to think about how to address this.

Most likely this is an issue with our font parser dependency. What version of opentype.js do you see works correctly?

I have an idea of the root cause (or at least one root cause). It's probably because the text processing code doesn't respect Cubics, only quadratic curves. TrueType only uses Quadratics but I believe newer font types (like open type) use Cubics. I'll add cubics to a branch and see if that fixes it.

This is what it looks like with the patch on the bug_144 branch. Much better, though now we can see that holes are filled

Not sure about the exact version of opentype.js I tested with. Just opened https://opentype.js.org/, chose the font file, and checked the render result.
