The new enum describes the nature of the failure. This is in
preparation for writing a replacement for SkImageDecoder, which will
use this interface.
Update the comments for getPixels() to specify what it means to pass
an SkImageInfo with a different size.
Make SkImageGenerator Noncopyable.
Leave onGetYUV8Planes alone, since we have separate discussions
regarding modifying that API.
Make callers of SkImageDecoder consistently handle kPartialSuccess.
Previously, some callers considered it a failure, and others considered
it a success.

SkTHashTable is very similar to SkTDynamicHash, except it's generalized to support non-pointer value types.
It doesn't support remove(), just to keep things simple (it's not hard to add).
Instead of an iterator, it has foreach(), again, to keep things simple.
SkTHashMap<K,V> and SkTHashSet<T> build a friendlier experience on top of SkTHashTable.

When checking the skia_arch_type for "x86", instead of doing an
== compare, check if "x86" in skia_arch_type, so it will cover
both x86 and x86_64.
Except when we specifically want x86.
Set skia_arch_width based on "64" in skia_arch_type. No need to specify
in scripts.
In gyp_to_android.py, create a separate var_dict for x86_64.

This has the side effect of requiring SkNullGLContext to use the null GL interface.
It exposes SkNullGLContext and also removes null context support from SampleApp.

This sets us up two new opts targets with the immediate goal of adding half-float (SkHalf.h) opts:
- opts_neon_fp16: uses hardware support on most ARM chips with NEON to do 4 conversions at a time;
- opts_avx: uses hardware support on Intel chips with AVX to do 8 conversions at a time.
opts_avx will be a handy thing to have around later too, especially if we want to work with floats.
This doesn't actually add any new source files to these libraries yet, so they're no-ops for now.
I'll need to write a parallel change to Chrome's GN and GYPs before we can start adding sources.
This also rolls GYP up to head, to get suppport for EnableEnhancedInstructionSet: '3' on Windows,
which is how we turn on AVX there. There's no Mac-specific flag, so we use OTHER_CPLUSPLUSFLAGS.

This merges and refactors SkAtomics.h and SkBarriers.h into SkAtomics.h and
some ports/ implementations. The major new feature is that we can express
memory orders explicitly rather than only through comments.
The porting layer is reduced to four template functions:
- sk_atomic_load
- sk_atomic_store
- sk_atomic_fetch_add
- sk_atomic_compare_exchange
From those four we can reconstruct all our previous sk_atomic_foo.
There are three ports:
- SkAtomics_std: uses C++11 <atomic>, used with MSVC
- SkAtomics_atomic: uses newer GCC/Clang intrinsics, used on not-MSVC where possible
- SkAtomics_sync: uses older GCC/Clang intrinsics, used where SkAtomics_atomic not supported
No public API changes.

Since we had such a hard time with the assembly versions of this blit (to the
point that we have them completely disabled everywhere), I thought I'd take
a shot at writing a version of the blit using intrinsics.
The key feature of SSE4 we're exploiting is that we can use ptest (_mm_test*)
to skip the blend when the 16 src pixels we consider each loop are all opaque
or all transparent. _mm_shuffle_epi8 from SSSE3 also lends a hand to extract
all those alphas.
It's worth looking to see if we can backport this type of logic to SSE2 using
_mm_movemask_epi8, or up to 32 pixels at a time using AVX.
My local performance testing doesn't show this to be an unambiguous win
(there are probably microbenchmarks and SKPs where we'd be better off just
powering through the blend rather than looking at alphas), but the potential
does seem tantalizing enough to let skiaperf vet it on the bots. (< 1.0x is a win.)
DM says it draws pixel perfect compare to the old code.

Since we had such a hard time with the assembly versions of this blit (to the
point that we have them completely disabled everywhere), I thought I'd take
a shot at writing a version of the blit using intrinsics.
The key feature of SSE4 we're exploiting is that we can use ptest (_mm_test*)
to skip the blend when the 16 src pixels we consider each loop are all opaque
or all transparent. _mm_shuffle_epi8 from SSSE3 also lends a hand to extract
all those alphas.
It's worth looking to see if we can backport this type of logic to SSE2 using
_mm_movemask_epi8, or up to 32 pixels at a time using AVX.
My local performance testing doesn't show this to be an unambiguous win
(there are probably microbenchmarks and SKPs where we'd be better off just
powering through the blend rather than looking at alphas), but the potential
does seem tantalizing enough to let skiaperf vet it on the bots. (< 1.0x is a win.)
DM says it draws pixel perfect compare to the old code.
Microbenchmarks:
bitmap_RGBA_8888_A_source_stripes_two 14us -> 14.4us 1.03x
bitmap_RGBA_8888_A_source_stripes_three 14.3us -> 14.5us 1.01x
bitmap_RGBA_8888_scale_bilerp 61.9us -> 62.2us 1.01x
bitmap_RGBA_8888_update_volatile_scale_rotate_bilerp 102us -> 101us 0.99x
bitmap_RGBA_8888_scale_rotate_bilerp 103us -> 101us 0.99x
bitmap_RGBA_8888_scale 18.4us -> 18.2us 0.99x
bitmap_RGBA_8888_A_scale_rotate_bicubic 71us -> 70us 0.99x
bitmap_RGBA_8888_update_scale_rotate_bilerp 103us -> 101us 0.99x
bitmap_RGBA_8888_A_scale_rotate_bilerp 112us -> 109us 0.98x
bitmap_RGBA_8888_update_volatile 5.72us -> 5.58us 0.98x
bitmap_RGBA_8888 5.73us -> 5.58us 0.97x
bitmap_RGBA_8888_update 5.78us -> 5.6us 0.97x
bitmap_RGBA_8888_A_scale_bilerp 70.7us -> 68us 0.96x
bitmap_RGBA_8888_A_scale_bicubic 23.7us -> 21.8us 0.92x
bitmap_RGBA_8888_A 13.9us -> 10.9us 0.78x
bitmap_RGBA_8888_A_source_opaque 14us -> 6.29us 0.45x
bitmap_RGBA_8888_A_source_transparent 14us -> 3.65us 0.26x
Running over our ~70 SKP web page captures, this looks like we spend 0.7x
the time in S32A_Opaque_BlitRow compared to the SSE2 version, which should
be a decent predictor of real-world impact.

SaveLayer (non-opaque)
Save
ClipRect
SaveLayer
Restore
Restore
Restore
Current blink generates these for example for SVG content such as this:
<path style="opacity:0.5 filter:url(#blur_filter)"/>
The outer save layer is due to the opacity and the inner one is due to
blur filter being implemented with picture image filter.
Reduces layers in desk_carsvg.skp testcase from 115 to 78.

To compile SkCondVar, we already require either pthreads or Windows. This
simplifies that code to not need SK_USE_POSIX_THREADS to be explicitly defined.
We'll just look to see if we're targeting Windows, and if not, assume pthreads.
Both before and after this CL, that code will fail to compile if we're not on
Windows and don't have pthreads.

This basically takes out the Windows-only hacks and promotes them to
cross-platform behavior driven by --gpu_threading.
- When --gpu_threading is false (the default), this puts GPU tasks and tests
together in the same GPU enclave. They all run serially.
- When --gpu_threading is true, both the tests and the tasks run totally
independently, just like the thread-safe CPU-bound work.

SkPDFCanon's fields and methods will eventually become part of
SkPDFDocument/SkDocument_PDF. For now, it exists as a singleton to
preflight that transition. This replaces three global arrays in
SkPDFFont, SkPDFShader, and SkPDFGraphicsContext. This code is still
thread-unsafe (http://skbug.com/2683), but moving this functionality
into SkPDFDocument will fix that.
This CL does not change pdf output from either GMs or SKPs.
This change also simplifies some code around the SkPDFCanon methods.

Make draw command image widget resize. The widget was not resizing,
effectively preventing the window from being resized smaller.
Make the rasterized draw command image be proportional to the widget
size. The draw rasterization canvas is still an equilateral rectangle
with dimensions of the smaller side of the widget.
Makes the widget re-rasterize the image only when the draw command
changes, not for each widget paint.
Renames the widget from "image widget" to "draw command geometry
widget".
Makes the background of the image black, similar to the raster widget
background.
Adds a tooltip saying "Command geometry" for the widget, so that user might
understand what the contents should be.
This commit is part of work that tries to make the debugger window to be
a bit more resizeable, so that it would fit 1900x1200 screen.

This GM is used to test the combined clipping of a complex clip (packman shape)
and a simple one (circle). We loop over all combinations of clip ops, aa/bw clip,
and inverse/non-inverse clips.
This GM triggers a current bug in the gpu clipping code which fires an assert. Thus
the skipGPU flag is set until that bug is fixed.

Like SkChunkAlloc, but
- does its allocation with better sympathy for malloc granularity;
- the fast path inlines entirely;
- smaller per-block overhead;
- smaller per-SkVarAlloc overhead;
- growth parameters are a little more tunable.
Its main downside is less flexibility; it supports fewer methods than SkChunkAlloc.
These current parameters bring the first allocation down from 4K to 1K,
