This patch improves the straight skeleton implementation used by
GrTessellator to collapse overlap regions in the alpha gradient border.
The resulting quality improvement can be seen in the
"thinconcavepaths" GM, for example, where the coverage values of
the "thin right angle", "thin rect and triangle" and "skinny snake"
are now lower and match the raster backend more closely. It also improves
correctness, such as on the linked Chromium bugs below.
Previously, the straight skeleton was performed using the same Vertex
and Edge classes used for tessellation, but this led to fragility in
maintaining the connectivity and ordering required by those classes.
Instead, that functionality has been moved to new SSEdge and SSVertex
classes. Their construction results in alternating SSVertex and
SSEdges around the boundary of the each overlap region, shrunk by one
SSEdge as the boundary collapses.
Applying events may now also create further events (chained events),
as intersections between newly-adjacent bisectors change the structure
of the skeleton. This is always calculated from the bisectors of
original boundary, not the shrunk boundary of the straight skeleton,
which is why each SSEdge points at its originating Edge. If the edges
are parallel or near-parallel, the bisector may be infinite. This is
handled by a new flavour of create_event(), which does a Line/Line
intersection (rather than an Edge/Edge intersection) to find the
intersection between the infinite bisector and an adjacent bisector.
Several ancillary bugs were fixed: the priority queue used to represent
edge events was sorting the inner edges incorrectly. These need to be
sorted in descending not ascending order of coverage. Its implementation
was moved from Skia's TDPQueue to std::priority_queue(), which is more
flexible in specifying a comparator.
check_for_intersection()'s partner synthesis code was moved into a new
function, compute_bisector(), also used by the chained skeleton events
code.
Degenerate edges are now removed during the simplify_boundary() pass.
They were previously detected but ignored, causing incorrect inner and
outer tangents to be computed in stroke_boundary().
An fSynthetic flag was added to Vertex, in order to detect vertices
which cannot be moved by an edge collapse event (e.g., intersections
with non-boundary edges, merged vertices, straight skeleton vertices).
More raw implementation notes:
Connect straight skeleton vertices as we find them, so we don't
have to use partnering (ss_connect()).
Only disconnect edges which are still alive after event application.
Add a check for near-parallel lines in compute_bisector().
Don't use edge type to determine direction to offset for bisectors.
The winding should already include this information.
Move Event ownership to SSEdge.
If we're down to the last two edges in a skeleton, don't check for events.
Add concave_arc_and_circle GM.
Add a collapsepaths GM.

We are planning to start detecting mipmaps and MSAA resolves during
the "gather" step now, so all visits should behave the same at this
point. (And it appears there might not have been any GrOps that
actually changed their behavior based on this flag at the moment.)
