.otf build has some characters with missing holes

[IdreesInc]

Describe the bug
The .otf build shows characters like 8, o, and O with filled in holes. This does not show up in the .ttf build for some reason.

Oddly enough, this is not on windows though.

I think it's because of differences in how the renderer treats holes. I suspect if the winding of holes is reversed it would solve it. Another solution is to merge polygons whenever possible. The latter is still being developed in my fork.

PS: Just tested reversing windings, it does not affect .otf, but it broke .ttf. Maybe try it just to be sure.
