Elias Naur 19f4d9fa95 change tile segment representation to (origin, vector) 
Eliminates the precision loss of the subtraction in the sign(end.x - start.x)
expression in kernel4. That's important for the next change that avoids
inconsistent line intersections in path_coarse.

Updates #23

Raph Levien af0a1af8e1 Make fills work 
The backdrop propagation is slow but it does work.

Raph Levien 294f6fd1db 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.
