Start image rendering Populates the piet-gpu subdir, with an extremely simple renderer. The main program saves the image to a PNG. Contains a few fixes (I was confused about the need for multiple bindings, as opposed to multiple descriptors within a binding).

# Build file for shaders.
# You must have glslangValidator in your path, or patch here.

Query extensions at runtime Don't run extensions unless they're available. This includes querying for descriptor indexing, and running one of two versions of kernel4 depending on whether it's enabled. Part of the support needed for #78

Experimenting with sort-middle Starting a prototype that explores the sort-middle approach. This commit has a prefix sum pass computing state per element.

Binning stage Adds a binning stage. This is a first draft, and a number of loose ends exist.

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.

Starting coarse rasterizer Working down the pipeline. WIP

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.
