Raph Levien 769d71915e Fetch correct query pool
It should fetch the last query pool, and was off by one. That worked on
my machine (windows), but did cause panics.

Raph Levien 75c4b62730 Add hub abstraction
The hub does a little better lifetime tracking of resources (so
Rust-side references can be dropped), and in the future will be used for
dynamic selection of backend.

The migration is still a bit half-baked, as there are a bunch of
Vulkan-specific types in the signatures, but it shouldn't be too much
work to sort that out. Perhaps it can wait until there is a second
backend though.

The main motivation for this is to create image objects with lifetime
tracking, one of the things required for #38.

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.

Raph Levien fe1790e724 Fix bbox bug
Bounding boxes were being calculated as way too large in the element
processing.

Also wire up counters so winit binary is happy.

Raph Levien 9a8854ffab Experimenting with sort-middle
Starting a prototype that explores the sort-middle approach. This
commit has a prefix sum pass computing state per element.
