Raph Levien e5dd9ae01e More parallel path coarse raster 
Use fancier load balancing algorithm for coarse rendering of paths.

Seems to work and an improvement in some cases.

Raph Levien 63ba45c774 Fix performance issues 
Use larger workgroup for tile initialization (utilization was poor).
Provide correct element count to coarse rasterizer.

Raph Levien ff8cee059c Optimize tile allocation 
Use parallel scheme to zero out tiles.

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.
