SampleApp now displays gamma-correct content in "S32" and "F16" modes. The default framebuffer is always (?) sRGB, but querying it to determine that is difficult or impossible. In addition, when running in "L32" mode, we stil want to exhibit the old behavior, where we pretended that it was not sRGB. Thus, set the pixel config of the render target based on the window's color and profile types. That triggers our code to turn on linear->sRGB conversion-on-write in flushRenderTarget.

NOte: Angle does not display correctly, due to limitations in the set of ES2 extensions it exposes. However, it can still be used to generate gamma-correct images (via DM, etc...).

Improve horizontal baseline detection.

The goal is to hint the baseline when hinting is possible, which is
to say when the glyphs are be aligned with the pixel grid. The
current code has three shortcomings.

1. correctly snaps when the horizontal baseline is on the x-axis but
not when on the y-axis. Instead it is snapping the horizontal
baseline when there is y-skew.

2. tests against the full device matrix instead of the relaxed
matrix used by the scaler context.

3. has range issues when relaxing the matrix.

This CL adds glTexStorage support.

For us to take advantage of immutable texture storage, we would need to
know in advance that the texture will not be changing allocated size.

In some cases we cannot know this in advance: we will sometimes later
need mipmaps to be allocated and generated. However, in the cases where
we know in advance that we are allocating mipmaps we can take advantage
of immutable storage.

Review URL: https://codereview.chromium.org/1751463002

Modernize SkSpinlock.

 - Use std::atomic directly.
 - No more need for SkPODSpinlock or SK_DECLARE_STATIC_SPINLOCK.

Now simple code like this works as you'd hope:
    static SkSpinlock gLock;

That is, it starts unlocked and there's no static initializer.

std::atomic_flag would make this terser and standard-guaranteed,
but ATOMIC_FLAG_INIT caused not-yet-implemented errors on MSVC 2013.
The generated code for this approach is identical.

It appears the implicit constructor is constexpr when all the member
initializers are.  I'm hoping this way of producing constexpr constructors
without typing "constexpr" gives us a way to eliminate more SkFoo / SkBaseFoo
distinctions and SK_DECLARE_STATIC_FOO.  This was certainly the easiest.

Revert of Enable RAW codec for Windows (patchset #8 id:140001 of https://codereview.chromium.org/1738913002/ )

Reason for revert:
I don't think there's anything wrong with this per-se, but the 32-bit Windows bots are running out of memory while running these tests now.

(You'll see something like c:\0\build\slave\workdir\build\skia\include\core\skbitmap.h:247: fatal error: ""sk_throw"" in the log.)

We run these tests in parallel, and sometimes these 32-bit processes try to use more than the 2-3G RAM they can allocate.  Seems like this is a particularly memory-intense process?

If we reland this, we might want to blacklist these tests on the 32-bit Windows bots.  The 64-bit bots should have access to tons and tons of RAM and let us keep testing for Windows.

Revert of Add non-inline SkRTreeFactory constructor to fix clang-cl (patchset #2 id:20001 of https://codereview.chromium.org/1676833002/ )

Reason for revert:
This workaround should no longer be needed, per comment#16 from
thakis@ on the original CL.

Original issue's description:
> Add non-inline SkRTreeFactory constructor to fix clang-cl
>
> When Chromium is switched to build with VS 2015 that switches clang-cl
> to build in -fmsc-version=1900 mode. This causes some changes in
> importing of constructors and vftables which leads to link errors in
> blink_platform.dll. Adding a non-inline constructor makes 1900 mode
> behave consistently with 1800 mode and avoids the link error.
>
> The root cause needs investigation but this will unblock the VS 2015
> switch.

DM: dm.json can be missing some final results

We called JsonWriter::DumpJson() every once in a while,
but this did not necssarily wait for offloaded PNG encoding to finish.

This means we might have been dropping some DM results for a while now.
Fix by one more JsonWriter::DumpJson() call after joining back to the
main thread.
