Faster sorting strategy, remove SortedVector

point_queue is only sorted by y coordinate to coordinate
work to one strip at a time. This is more efficiently handled
by punting later work into a next_point_queue,
and never explicitly sorting the data.
active_edges is only sorted by x coordinate for the tile-by-tile
work in process_old_active_edges. It is much more efficient
to sort once inside that function.

Implement the HSL filters (called "non-separable blend modes" in the spec).

67d12adb6c
Replace layers with render targets, which can be used as patterns.
...
This allows us to efficiently handle a lot of workloads that require multiple
HTML canvases, without CPU readback. For example, you can render paths to a
render target, then turn that render target into a repeating pattern that you
fill other paths with. Or you can render paths to a render target and then
composite that render target as a whole with a blend mode.
This introduces a new `DrawRenderTarget` render command that blits a render
target without any paths involved. This is basically just a hack that works
around the fact that our tiled renderer doesn't yet support effects that widen
the ink region (i.e. blurs). It can be removed once we have that support.
