A stroked arc with round caps was batched with a filled circle. The circle op
code would choose a GeometryProcessor configuration that expected round cap
centers as vertex attributes. However, the tessellation code for the filled
circle would not put in dummy round cap centers and then didn't advance the
pointer into which vertex data was being written by the expected vertex
stride.

This separates the existing convexity logic into
two passes. The first pass detects concavity by
counting the changes in direction.
The second pass computes the cross product to
see that all angles bend in the same direction, and
computes the dot product to see if the angle
doubles back on itself.
The second pass treats axis-aligned vectors
separately, and computes the dot and cross products
by comparing point values; it does not use arithmetic
to determine convexity, so it works with all finite
values.
A compile time switch enables returning concave
for co-linear diagonal points:
If successive points are not axis-aligned, and
those points are co-linear along a diagonal;
the path is treated as concave. This is conservative
but avoids paths that change convexity when the
are translated or scaled, since transforming the
path may cause the midpoint to shift to either
side of a line formed by the endpoints.
The compile time switch is set so that co-linear
diagonal points do not affect convexity. Note that
this permits shapes formerly considered concave, such
as stroked lines with round caps, to become convex;
this accounts for many of the GM differences.
A path may double back on itself and be convex;
for instance, a path containing a single line.
Path may have multiple initial moveTo verbs, or
trailing moveTo verbs, and still evaluate as convex.
A separate entry point, SkPathPriv::IsConvex()
allows passing an array of points instead of a path.
A legacy define has been checked into Chrome to
use the old code until layout tests have been
rebaselined.

Added a GM that demonstrates the bug. Should draw a blur with
the center masked out, and a circular blurry shape that's
roughly the inverse. On raster, this was already the result.
On GPU, the blurred/eroded layer becomes a subset with an
origin other than (0,0), and that layer was shifted.
I *think* this is the correct fix - we are including 'offset'
in the texture matrices, but that's just based on the crop
rects and adjustments from each filter. We still need to adjust
the texture coords for the subsets themselves.

GrRenderTargetOpList maintains an array of op chains. When it receives a
new op it tries to add it to an existing chain, working backwards from
the end of the current array. If the op can be added to a chain it
additionally tries to merge the new op with ops already in the chain
before adding it to the tail of the chain.
In forward combining it tries to concatenate chains. If chains can
concatenate it also attempts to merge ops between the two chains.
Now op chaining results reported by Op subclasses must be transitive.
Moreover, if op A is able to merge with B then it must be the case that
any op that can chain with A will either merge or chain with any op that
can chain to B.
