This will expose the BitmapRegionDecoder API as a public include
and move the implementation to src.
This makes this code more naturally exposed in Android and easier
to test in DM and nanobench.

Rename SkCodecTools.h to SkBitmapRegionDecoderPriv.h
Move BRD code to its own directory in tools. This
allows us to not need to expose the entire tools
directory in Android.

SkBitmapRegionDecoderInterface provides an interface
for multiple implementations of Android's
BitmapRegionDecoder.
We already have correctness tests in DM that will enable us
to compare the quality of our various BRD implementations.
We also need these performance tests to compare the speed
of our various implementations.

I'll be moving headers from src/core to include/private, so this guarantees
that anyone who was finding them via -Isrc/core can now find them via
-Iinclude/private.
This is purely mechanical, mostly to preserve my sanity, so it's likely
(harmless) overkill.
Chromium's GYP and GN builds already set -Iinclude/private for Skia builds.

Some of this is transitive, like SkRecords.h used by SkMiniRecorder.h
used by (public) SkPictureRecorder.h.

I'm thinking of using this in perf with something like:
ratio(fill(filter("test=foo")), fill(filter("test=control")))
Does that make sense to you?
Not sure that this is really a good control bench on all bots,
but I propose we just run it a bit and find out if it needs work.

For the added bench, the collapsing makes the bench take:
- 70% of the time for CPU rendering of 3 consecutive matrix filters
- almost no change in the GPU rendering of the matrix filters
- 50% of the time for CPU and GPU rendering of 3 consecutive table filters

Draw thick-stroked Beziers by computing the outset quadratic, measuring the error, and subdividing until the error is within a predetermined limit.
To try this CL out, change src/core/SkStroke.h:18 to
#define QUAD_STROKE_APPROXIMATION 1
or from the command line: CPPFLAGS="-D QUAD_STROKE_APPROXIMATION=1" ./gyp_skia
Here's what's in this CL:
bench/BezierBench.cpp : a microbench for examining where the time is going
gm/beziers.cpp : random Beziers with various thicknesses
gm/smallarc.cpp : a distillation of bug skia:2769
samplecode/SampleRotateCircles.cpp : controls added for error, limit, width
src/core/SkStroke.cpp : the new stroke implementation (disabled)
tests/StrokerTest.cpp : a stroke torture test that checks normal and extreme values
The new stroke algorithm has a tweakable parameter:
stroker.setError(1); (SkStrokeRec.cpp:112)
The stroke error is the allowable gap between the midpoint of the stroke quadratic and the center Bezier. As the projection from the quadratic approaches the endpoints, the error is decreased proportionally so that it is always inside the quadratic curve.
An overview of how this works:
- For a given T range of a Bezier, compute the perpendiculars and find the points outset and inset for some radius.
- Construct tangents for the quadratic stroke.
- If the tangent don't intersect between them (may happen with cubics), subdivide.
- If the quadratic stroke end points are close (again, may happen with cubics), draw a line between them.
- Compute the quadratic formed by the intersecting tangents.
- If the midpoint of the quadratic is close to the midpoint of the Bezier perpendicular, return the quadratic.
- If the end of the stroke at the Bezier midpoint doesn't intersect the quad's bounds, subdivide.
- Find where the Bezier midpoint ray intersects the quadratic.
- If the intersection is too close to the quad's endpoints, subdivide.
- If the error is large proportional to the intersection's distance to the quad's endpoints, subdivide.

drawPatch now receives as parameter const SkPoint cubics[12]
Adjusted derived classes and serialization.
Ajusted GM's and benches that take into account combinations of optional
parameters, the scale of the patch and 4 different types of patches.
Planning on adding the extra functionality of SkPatch in another CL.

First bench: Simply render from a compressed ETC1 bitmap. This is roughly
equal between compressed and uncompressed data.
Second bench: Notify the bitmap that the pixels have changed (that's right,
like a liar) to force a re-upload to the GPU. On this bench, decompressed
textures seem to inexplicably do an order of magnitude better than
compressed textures when it should be the other way around, but that
investigation is reserved for a future CL.
