Reason for revert:
More GMs changed than I expected. Will probably affect layout tests as well; reverting until I can verify that the changes are correct.

If the endcap is not butt, draw the endcaps even when the line
has zero length.
If the dash length is zero, generate a zero length line segment.
Treat a move followed by a close as a move followed by a zero-length
line.

SkXfermodeImageFilter::filterImageGPU is the only call site that does anything fancy when getInputResultsGPU fails. It seems like we can just return like everyone else (for uniformity).

Minimize the number of stencil writes by using GL_KEEP whenever possible.
This can positively affect the HW performance of the stencil test.

Clip using a geometric solution if the algebraic solution
fails in Y as well as in X.
If the root finder discovers real roots that are sufficiently
far apart, the root in the range of 0..1 can contain so much
error that it is computed to be slightly smaller than 0 or
larger than 1.
In this case, binary search the mono curve for the actual
answer.

Reason for revert:
This causes a syntax error.

Please review concept; I'm OK not to check this in.
If the root finder fails, subdivide the curve and try again.
This is complicated by the reversed nature of the curves;
maybe it can be simpler, but how to do that escapes me.

Image filters have never implemented this check, which means that
filters which affect transparent black falsely claim they can compute
their bounds.
Implemented an affectsTransparentBlack() virtual for image
filters, and a similar helper function for color filters.
This will affect the following GMs: imagefiltersscaled
(lighting, perlin noise now filter to clip),
colorfilterimagefilter (new test case), imagefiltersclipped
(perlin noise now filters to clip).
Note: I de-inlined SkPaint::canComputeFastBounds() to avoid adding
a dependency from SkPaint.h to SkImageFilter.h.h. Skia benches show
no impact from this change, but will watch the perf bots carefully.

Annoyingly our test bot that forces SkPMFloat_none is a Linux bot using
BGRA SkPMColors, so we'd never notice the bug there.

Compress SkPDFStream's data on setData(), not emitObject(); no longer stateful.
SkPDFObject::emitObject is now const. This makes it easier to reason about state.
Minimal performance gains.

SkTemplates.h contains a number of Skia specific utilities which are
not designed for external use. In addition to reducing the external
support burden, this will allow Skia to freely refactor this file.
