Replace the MCAA shader with an extended Loop-Blinn approach and an

approximation of area based on approximate first-order line distance.
This enables support for full affine transforms in MCAA. It also greatly

to do for fragment shading.
Experimental testing has shown the area approximation to be accurate to
about 4%.

Port Pathfinder to use Lyon for Bézier curve math.
...
This removes a whole lot of code from `pathfinder_path_utils`. Hopefully
the remaining code can go upstream.
These changes regress quality of stroke widths for cubic curves, because
they move fill-to-stroke conversion before cubic-to-quadratic
conversion. To fix that, we will need to recursively subdivide when
doing fill-to-stroke conversion.

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.
