? It's target is you, the cairo developer, to compare against the things
that skia does better whilst being constrained to the same pdl as cairo.
Hence experimental. Carrying it should have very little maintenance
burden (since it is not marked as being maintained), yet reduce the cost
of such experiments by allowing/encouraging collaboration

Skia is smarter at handling splines, tight generation of rasterisers and
sources (benefiting from having its pixman integration). In short, it
does a lot better than Cairo in many circumstances; where Cairo used to
have an advantage was areas such as decomposing paths in faster
primitives, pixman had more acceleration paths.
