f132117d4c
Don't add overlapping points to close paths in the stroking algorithm.
...
These extra points are unnecessary and can confuse the partitioner,
because they sometimes prevent it from detecting winding numbers
properly. This is a bug in the partitioner and should be fixed, but we
shouldn't be generating these points to begin with.
Partially addresses #57 .

cfe72f486e
Use a single-pass pixel-snapping MCAA algorithm instead of a multipass
...
ECAA algorithm for multicolor SVG.
This is much faster than both Skia and the previous XCAA algorithm
while maintaining slightly higher quality than the latter.
There are a couple of known issues:
* Vertical inflection points of hairlines with very steep slopes can
become very light or even drop out occasionally. I suspect this is due
to floating point error.
* Rarely, single columns of pixels can disappear from a mesh. Cause TBD.
Besides these bugs, this technique can be cleaned up and probably made
faster, but it's a sizable improvement as is.
