The cache is scoped with the SkColorSpaceXformer object.
This ensures we're not transforming nodes with a degree > 1 multiple
times, and preserves the DAG topology.

Impl Overview
(1) Keep the device clip bounds up to date. This
requires minimal additional work in a few places
throughout canvas.
(2) Keep track of if the ctm isScaleTranslate. Yes,
there's a function that does this, but it's slow
to call.
(3) Perform the src->device transform in quick reject,
then check intersection/nan.
Other Notes:
(1) NaN and intersection checks are performed
simultaneously.
(2) We no longer quick reject infinity.
(3) Affine and perspective are both handled in the slow
case.
(4) SkRasterClip::isEmpty() is handled by the intersection
check.
Performance on Nexus 6P:
93.2ms -> 59.8ms
Overall Android Jank Tests Performance Impact:
Should gain us a ms or two on some tests.

Before the fix, we could use a stale cache of the clipbounds in quickReject. Often this could return false negatives, meaning we would try to draw more than we should (it would eventually be really clipped). Occasionally this could also report false positives (if the layer were outside of the normal canvas bounds, e.g. a layer with an offset imagefilter).

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.
for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end

There are only a handful of SkFlattenables that are not flattenable. That
there are any seems highly illogical. To make this look less like a normal
thing, this removes both macros that marked SkFlattenables as non-flattenable
(in slightly different ways).
The handful of SkFlattenables in our codebase that can't be flattened now
assert violently that they can't be flattened. They're internal or
part of animator... places where we'll never actually flatten them.
TestLooper and DummyRasterizer were so trivial that I just made them flattenable.
