Many times a pair of stroked line segments doesn't actually require the
inner "loop" geometry. I think I've classified where it's required into
two cases.
This CL checks for the two cases where it is necessary, and skips adding
the extra geometry if not necessary. Requires a few extra
multiplications.

I figure we can use this as an area for prototyping new/different
stroker ideas.
Currently the sample does line segments with butt caps. Miter joins
aren't correct, as it's not adding the inner loop geometry that
SkPathStroker does. On the sample slide, any red pixels are ones that
Skia filled but the toy stroker didn't.

Mostly this is a lot of plumbing of sk_sp around instead of const*.
This does allow the d3d and vk backends to hold refs to the GrBuffers that
are bound on a command buffer. This means that our buffer alloc pools will
not try to reuse this buffers until the gpu is done with them. Previously
vk and d3d will sniff out if one of these buffers was being used again
while still active on the gpu and rip out the internal backend buffer and
allocate a new one which is not cheap. We see a lot of perf wins from
not doing this.

Fits a cubic to an arc on the unit circle using the following
constraints:
1) The endpoints and tangent directions at the endpoints must match
the arc.
2) The cubic must be symmetric (length(p1 - p0) == length(p3 - p2)).
3) The height of the cubic must match the height of the arc.
Using the above constraints, we arrive at the following formula for the
control length (c) (i.e., lengths of (p1 - p0) and (p3 - p2)):
d = x0*x1 + y0*y1
c = (sqrt(1 + d) * kM + kA) * rsqrt(1 - d)
(Where x0,y0,x1,y1 are the endpoints, kM = -4/3, and kA = 4/3 * sqrt(2).)
The sample also comes with a root finder that finds the max error value
of the curve, which ends up serving as a semi-formal proof that:
1) Max error always occurs at T=0.21132486540519, regardless of
endpoints.
2) Error is reduced by exactly 64x each time we halve the arc angle

Adds a method to determine the worst-case number of tessellated line
segments that a path might require, and disables hardware tessellation
if it is more segments than are supported (falling back on indirect
draw shaders).
If the path requires even more segments than are supported by the
indirect draw shaders (1024), we crop the path to the viewport. The
required number of segments is proportional to the square root of the
bounding box's diagonal, so we won't start cropping paths until their
device-space bounding box diagonal is nearly 175,000 pixels long.

C++:
canvas->concat(...);
canvas->markCTM("localToWorld");
canvas->concat(...);
canvas->drawFoo(...);
Any runtime effects created with that SkSL will have their
localToWorldMatrix uniform filled in with the CTM, ignoring
any transformation that happened before/above the markCTM
call. The marker needs to be a sequence of alphanumeric or
underscore characters, and match the string used in markCTM.
The marker can also be of the form "normals(<string>)", in
which case the uniform will be filled in with the transpose
of the inverse of the upper-left 3x3 portion of the CTM
identified by <string>. This is helpful for transforming
normal vectors, as is often done in lighting.
