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.

The existing logic looks wrong to me:
- clamp premul to [0,1]
- unpremul, ignoring zero alpha
It seems like we should do:
- unpremul, avoiding any divide by zero
- clamp unpremul to [0,1]
Am I misunderstanding this or has this just always been wrong?

Handle the case where the an intersection falls not only above both
edge endpoints, but above the first vertex in the mesh. This requires
passing the mesh into check_for_intersection(), in order to modify the
head. We also need to rewind the mesh after insertion, since we need
to rewind to the newly-inserted vertex.
This also cleans up vertex ID computation a little (for logging), so
that vertices before the first vertex or after the last have a
reasonable ID. It also cleans up the intersection-on-endpoint
special cases by refactoring the calls to split_edge().

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.)

The coverage blitter is an optimization of regular blitting to A8.
It can go faster because it never tries to blend with itself... because
it was intended to be called only by fill-path, which is written to
never draw twice in the same place. Hairlines don't make this promise,
so we can use the coverage optimization for hairlines.
