Moves cubic root finding logic out of GrPathUtils and
PathOpsCubicIntersectionTest, and unifies it in SkGeometry.
"Normalizes" the homogeneous parameter values of the roots, rather
than the cubic inflection function. Does this normalization by
twiddling the exponents instead of division (which causes a loss of
precision).
Abandons the built-in derivatives in GrCubicEffect. These don't have
high enough precision on many mobile gpus. Instead we pass the KLM
matrix to the vertex shader via uniform, where we can use it to set up
new linear functionals from which the fragment shader can calculate
the gradient of the implicit function.

SkCodec sets fRequiredFrame to be the earliest possible frame that a
given frame can depend on. e.g.
- Frame A fills the screen, Keep
- Frame B does not cover A, Keep
- Frame C covers B but not A, and is opaque
Frame C can depend on either A or B. SkCodec already reports that C
depends on A. This CL allows a client of SkCodec to use either A or
B to create C.
Also expose the DisposalMethod. Since any frame between A and C can
be used to create C except for DisposePrevious frames, the client
needs to be able to know the disposal method so they do not try to
use such a frame to create C.
Further, the disposal method can be used to give the client a better
idea whether they will continue to need a frame. (e.g. if frame i is
DisposePrevious and depends on i-1, the client may not want to steal
i-1 to create i, since i+1 may also depend on i-1.)

Since this GM isn't testing the GPU rendering of the mips, this workaround is

Due to floating point inaccuracy, when intersecting edges, the
intersection point may fall above one of the edges' top vertices
or below one of the bottom vertices. In these cases, we were simply
splitting one edge on the relevant endpoint of the other edge. This
is incorrect if the intersection is far from the endpoint (e.g.,
the test case in the linked bug, where one of the intersected edges
is near-horizontal but the intersection falls below both of its
endpoints, in the middle of the edge.)
The correct solution is to split both edges as normal, and take care
to produce edges with the correct ordering where the intersection is
above or below an edge. However, since the new vertex may be above
the current vertex, simply restarting intersection checks at the
current vertex won't work. We need to process the intersection
vertex before the current one.
This introduces another problem: unlike all other splitting modes
(which always shorten edges), splitting an edge above the top or
below the bottom can lengthen it, causing it to violate the AEL
with an adjacent edge which then shortens it back to the original
point (in cleanup_active_edges()). Since the splitting and merging
code can't agree, we loop forever.
Instead of simply fusing neighboring edges in cleanup_active_edges(),
the proper fix to this problem is to detect the AEL violation and
rewind all processing to the vertex above it. For performance, we
only rewind when we detect that a split edge is no longer ordered
within the mesh (merge_enclosing_edges()) or within the the AEL
(rewind_if_necessary()). We also store the enclosing edges of each
vertex, which allows us to rewind quickly, since we know exactly which
edges need to be added/removed from the AEL.
cleanup_active_edges(), fix_active_state() and Vertex::fProcessed have
been removed. In their place are rewind_active_edges() and
rewind_if_necessary(), which uses the same logic as
cleanup_active_edges() but uses it to know when to rewind.

This demonstrates a new kind of hybrid unit test/GM.
It creates a grid of cells. In each cell, we do two
renders that are expected to produce the same result.
For each cell, we render the two results overlaid,
and highlight any differing pixels in red. Assuming
there is a diff, the area around the largest diff
is drawn zoomed in from both images.
Matching cells are outlined in green, failing cells
are outlined in red. Triaging this GM just involves
