Continue building out pipeline
...
Plumbs the new tiling scheme to k4. This works (stroke only) but still
has some performance issues.

Experiment with new sorting scheme
...
Path segments are unsorted, but other elements are using the same
sort-middle approach as before.
This is a checkpoint. At this point, there are unoptimized versions
of tile init and coarse path raster, but it isn't wired up into a
working pipeline. Also observing about a 3x performance regression in
element processing, which needs to be investigated.

Start work on parallel segment output
...
Output of segments is in parallel. Getting closer, some problems with
chaining but mostly correct.

Rework right_edge computation in elements
...
Trying to fit it into the fancy monad doesn't really work, so use a
more straightforward approach to compute it from the aggregate.
Also add yEdge logic (basically copying piet-metal). With a fix to
ELEMENT_BINNING_RATIO (which I had simply gotten wrong), the example
renders almost correctly, with small bounding box artifacts.

Start implementing fills
...
This should get the "right_edge" value for each segment plumbed through
to the binning phase. It also needs to be plumbed to coarse raster and
wired up there.
Also considering WIP because none of this logic has been tested yet.
