3 people a5e378fd4b M3: tiles skip paths that can't paint them (item 5 of #623) (#670) ...

A tile of a large page renders the whole page with an offset, and hayro
stroked and filled every path on it before vello discarded what fell
outside the tile. Vendored hayro patch (9), `may_paint_canvas`, skips a
fill or stroke whose box misses the canvas: the box of the path's points
and control points (a curve stays inside their hull), grown by the
stroke's reach (half the width times the larger of the miter limit and
sqrt 2), by 0.5 user units for vello's and kurbo's approximation
tolerances, and by 2 device pixels for antialiasing. Empty paths and
non-finite bounds or miter limits are always drawn.

Renders are byte-identical with and without skipping
(`skipping_paths_off_the_canvas_changes_no_pixel`; the hidden per-thread
`set_skip_offscreen_paths` exists for that test). On #623's sample at
scale 2, a 1024 px tile takes about 38% less CPU time; whole pages are
unchanged.
