'static const' means, there must be at most one of these, and initialize it at
compile time if possible or runtime if necessary. This leads to unexpected
code execution, and TSAN* will complain about races on the guard variables.
Generally 'constexpr' or 'const' are better choices. Neither can cause races:
they're either intialized at compile time (constexpr) or intialized each time
independently (const).
This CL prefers constexpr where possible, and uses const where not. It even
prefers constexpr over const where they don't make a difference... I want to have
lots of examples of constexpr for people to see and mimic.
The scoped-to-class static has nothing to do with any of this, and is not changed.
* Not yet on the bots, which use an older TSAN.

SkMatrix::scale and ::rotate take a point around which to scale or rotate.
Canvas lacks these helpers, so the code to rotate a canvas around a
point has been duplicated many times. Factor all of these
implementations into SkCanvas::rotate.

The hintgasp font was added specifically for the typefacerendering gm.
However, this gm didn't actually use the font, so now use it. In
addition this adds embedded bitmap strikes to the hintgasp font and the
gm is updated to test these as well.

Constructing the gm tests and benches causes many calls to font loads.
This is visible as profiling samples in fontconfig and freetype on Linux
for all profiling runs of nanobench. This complicates analysis of
test-cases that are suspected of being slow due to font-related issues.
Move the font loading to GM::onOnceBeforeDraw and Benchmark::onPreDraw.
This way the code is not executed if the testcase does not match the
nanobench --match filter. This way the samples in font-related code are
more easy to identify as legitimate occurances caused by the testcase.
This should not cause differences in timings, because:
* Benchmark::preDraw / onPreDraw is defined to be run outside the timer
* GM::runAsBench is not enabled for any of the modified testcases. Also
nanobench untimed warmup round should run the onOnceBeforeDraw.
(and there are other GM::runAsBench gms already doing loading in
onOnceBeforeDraw).
Changes the behavior:
In TextBench:
Before, the test would report two different gms with the same name if
the color emoji font was not loaded successfully.
After, the test always reports all tests as individual names.
Generally:
The errors from loading fonts now print inbetween each testcase, as
opposed to printing during construction phase. Sample output:

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

Allow GM results to be compared across machines and platforms by
standardizing the fonts used by all tests.
This adds runtime flags to DM to use either the system font context (the
default), the fonts in the resources directory ( --resourceFonts ) or a set
of canonical paths generated from the fonts ( --portableFonts ).
This CL should leave the current DM results unchanged by default.
If the portable font data or resource font is missing when DM is run, it
falls back to using the system font context.
The create_test_font tool generates the paths and metrics read by DM
with the --portableFonts flag set, and generates the font substitution
tables read by DM with the --resourceFonts flag set.
If DM is run in SkDebug mode with the --reportUsedChars flag set, it
generates the corresponding data compiled into the create_test_font tool.
All GM tests set their typeface information by calling either
sk_tool_utils::set_portable_typeface or
sk_tool_utils::portable_typeface .
(The former takes the paint, the latter returns a SkTypeface.) These calls
can be removed in the future when the Font Manager can be superceded.

Also make SkGPipeController ref the recording canvas to ensure that
objects used by SkGPipeCanvas (e.g. SharedHeap and fTypefaceSet, which
hold references to objects to which pointers are written to the stream)
survive to be played back even if SkGPipeWriter.endRecording() is called.
