Catapult (Chrome tracing) has a hard upper limit of 256 MB of JSON data.
This is independent of the number of events, because V8 can't store a
single string longer than that. Before these changes, longer traces
(eg all GL GMs, which was my test case) would be much larger (306 MB).
This CL includes four changes that help to reduce the text size:
1) Offset timestamps (saved 7.3 MB)
2) Limit timestamps and durations to 3 digits (saved 10.7 MB)
3) Shorten thread IDs (saved 7.2 MB)
4) Omit categories from JSON (saved 25.7 MB)
Note that category filtering still works, this just prevents us from
writing the categories to the JSON, which was of limited value.
At this point, my 306 MB file is now 255.3 MB, and loads.

This new source acts like other sources (GMs, SKPs) for benchmarks. It
times multiple samples (controlled by samples=N, default 20), and each
of those samples uses the same strategy as monobench, growing loops
exponentially until it runs for at least 10ms.
When done it prints the fastest and the two slowest samples. In
practice the 100th percentile sample is very different from the
next slowest due to caching, and the fastest is always interesting.
Because these benchmarks run in whatever execution engine ok has
selected, on non-Windows platforms you have some real control over the
interaction between benchmarks. In its default "fork" mode each
benchmark runs independently in its own process, so the 100th
percentiles really stand out. The other modes "thread" and "serial"
work as you'd expect too.
Here's an example where you can see how the different interactions work:
out/ok bench:samples=100 8888 filter:search=text_16_AA fork
[text_16_AA_WT] 2.32µs @0 6.23µs @99 24.3ms @100
[text_16_AA_FF] 2.41µs @0 5.7µs @99 23.3ms @100
[text_16_AA_88] 2.55µs @0 5.6µs @99 24.8ms @100
[text_16_AA_BK] 1.97µs @0 5.44µs @99 23.2ms @100
out/ok bench:samples=100 8888 filter:search=text_16_AA thread
[text_16_AA_FF] 2.45µs @0 23.5µs @99 24.8ms @100
[text_16_AA_WT] 2.52µs @0 17.8µs @99 24.7ms @100
[text_16_AA_88] 2.55µs @0 19.7µs @99 25.1ms @100
[text_16_AA_BK] 1.8µs @0 14.7µs @99 25.1ms @100
out/ok bench:samples=100 8888 filter:search=text_16_AA serial
[text_16_AA_88] 2.35µs @0 3.53µs @99 16.7ms @100
[text_16_AA_FF] 2.09µs @0 2.73µs @99 2.91µs @100
[text_16_AA_BK] 1.75µs @0 2.46µs @99 2.65µs @100
[text_16_AA_WT] 2.1µs @0 3.16µs @99 3.17µs @100
In the first "fork" case all runs are independent and have roughly
the same profile. "thread" looks similar except you can see them
contending at the 99th percentile. In "serial", the first bench
warms up the rest, so their 100th percentiles are all much faster.

This is a stand-alone helper class for writing properly
structured JSON to an SkWStream. It currently solves two
problems (although this CL only uses it in one context):
1) Performance. Writing out JSON this way is about 10x
faster than using JSONCPP. For the large amounts of data
generated by the tracing system, that's a big win.
2) Makes it easy to emit structured JSON from code that's
not fully centralized. We'd like to spit out JSON that
describes a GrContext, GrGpu, GrCaps, etc... Doing that
with simple string manipulation is complex, and spreads
this logic over all those functions. Using JSONCPP adds
yet another (large) third party library dependency (that
we only build into our own tools right now).
This went through several revisions. I originally planned
it as a stateful SkString wrapper, so the user could just
build their JSON as a string. That's O(N^2), though,
because SkString grows by a (small) constant amount. Even
using a better growth strategy still means needing RAM
for all the resulting text, which is usually pointless.
This version has a constant memory cost, so writing huge
amounts of JSON to disk (tracing a long DM run can emit
100's of MBs) doesn't stress resources.

DAA is:
1. Much simpler than AAA.
SkScan_AAAPath.cpp is about 1700 lines.
SkScan_DAAPath.cpp is about 300 lines.
The whole DAA CL is only about 800 lines.
2. Much faster than AAA for complicated paths.
The speedup applies to GL backend (including ccpr)!
Here's the frame time of 'SampleApp --slide Chart' on macbook pro:
AAA-raster: 33ms
DAA-raster: 21ms
AAA-gl: 30ms
DAA-gl: 20ms
AAA-ccpr: 18ms
DAA-ccpr: 12ms
My linux desktop doesn't have SSE3 so the speedup is smaller
(~25% for Chart). I believe that DAA is so fast that I can enable
it for any paths (AAA is not enabled by default for complicated
paths because it is slow; hence our older supersampling scan
converter is used for stroking on Chart for AAA-xxx config.)
3. The SkCoverageDelta is suitable for threaded backend with
out-of-order concurrent scan conversion as commented in the source
code. Maybe we can also just send deltas to GPU.
4. Similar to most analytic path renderers, the quality is on the best
ground-truth level, unless there are intersections within a pixel.
The intersections look good to my eyes although theoretically that
could be arbitrary far from the ground truth (see my AAA slides).
5. For simple paths, such as circle, triangle, rrect, etc., DAA is
slower than AAA. But DAA is faster than our older supersampling
scan converter in most cases. As those simple paths usually don't
constitute the bottleneck of a picture (skp or svg), I strongly
recommend use DAA.
6. DAA also heavily favors blitMask so it may work quite well with
SkRasterPipeline and SkRasterPipelineBlitter.
Finally, please check https://skia-review.googlesource.com/c/22420/
which accelerate DAA by specializing blitCoverageDeltas for
SkARGB32_Blitter and SkARGB32_Black_Blitter. It brings a little(<5%)
speedup. But I couldn't figure out how to reduce the duplicate code
so I don't intend to land it.

This doesn't do anything in the default process-per-task mode, because
those child tasks exit using _exit(), which doesn't trigger the event
tracer destructor to flush.
I don't remember exactly why I exit with _exit(), so I'm going to have
to follow up on that. But written this way as I think I'm at least
initializing the tracing in the right place for each process for the
future.
In threaded (-j -1) and serial (-j 0) modes, everything seems to work
great.
I'm also thinking I might add a tracer like the SkDebugf tracer but
using ok_log(), which handles interlaced logging from concurrent tasks
better than vanilla SkDebugf.

ninja -C out ok; and out/ok gm 8888 filter:search=fontmgr_bounds trace -j -1

There is now one tracing flag: 'trace'.
- 'debugf' installs the SkDebugf tracer.

- Any other value is interpreted as a filename, and
produces a JSON file for chrome://tracing.
All three modes work in DM, nanobench, and Viewer.
