472ab81032 abort really big path fuzzing
This adds a couple of special cases
to stop the fuzzer from timing out.

The first occurs when the fuzzer generates
a very large path with very large quads.
Count the subdivisions and stop after a while.

The second occurs with a normal path and
1D path effect with a very small advance.
Count the points and stop after a while.

689d02d4b4 harden pathmeasure and fix empty case
change int to unsigned (just make it uniform,
part of it was already unsigned)

change path by pointer to path by value
since it will be copied on write; fixes bug
where path changes from underneath measure

Allow empty paths to still initialize measure state.
This fixes the GM failure from the earlier check-in attempt
in CL 113269.

1a7eb26664 resolution dependent path measure
When a dash is drawn through a canvas with a scaled up
matrix, path measure needs the pixel resolution through
the matrix to construct the dash with sufficient
resolution.

Pass the resolution through to path measure.

Replicate chrome bug in skia GM.

b6474dd1a5 fix circular dashing
Path measure cannot use the same code approach for quadratics
and cubics. Subdividing cubics repeatedly does not result in
subdivided t values, e.g. a quarter circle cubic divided in
half twice does not have a t value equivalent to 1/4.

Instead, always compute the cubic segment from a pair of
t values.

When finding the length of the cubic through recursive measures,
it is enough to carry the point at a given t to the next
subdivision.

(Chrome suppression has landed already.)
