Moves the coverage logic into GrGLXferProcessor for XPs that perform
dst reads. XPs that don't use a dst read are still responsible to
handle coverage on their own.

Long lived SkImageHeap objects currently accumulate refs indefinitely.
This leads to massive memory leaks in the gpu-accelerated 2D canvas
code path. This CL does not implement a general fix for SkGPipe, but
it resolves the leak in SkDeferredCanvas (currently the only user
of SkGPipe) by resetting the image heap when the deferral queue is
flushed. This change also fixes the accounting of bytes allocated
by referenced images in order to trigger flushing heuristics
appropriately.

Removes the runtime logic used by PorterDuffXferProcessor to decide
blend coeffs and shader outputs, and instead uses a compile-time
constant table of pre-selected blend formulas. Separates out the dst
read fallback into its own XP.
Introduces a new blend strategy for srcCoeff=0 that can apply coverage
with a reverse subtract blend equation instead of dual source
blending.
Adds new macros in GrBlend.h to analyze blend formulas both runtime.
Removes kSetCoverageDrawing_OptFlag and GrSimplifyBlend as they are no
longer used.
Adds a GM that verifies all xfermodes, including arithmetic, with the
color/coverage invariants used by Porter Duff.
Adds a unit test that verifies each Porter Duff formula with every
color/coverage invariant.
Major changes:
* Uses a reverse subtract blend equation for coverage when srcCoeff=0
(clear, dst-out [Sa=1], dst-in, modulate). Platforms that don't
support dual source blending no longer require a dst copy for
dst-in and modulate.
* Sets BlendInfo::fWriteColor to false when the blend does not modify
the dst. GrGLGpu will now use glColorMask instead of blending for
these modes (dst, dst-in [Sa=1], modulate ignored for [Sc=1]).
* Converts all SA blend coeffs to One for opaque inputs, and ISA to
Zero if there is also no coverage. (We keep ISA around when there
is coverage because we use it to tweak alpha for coverage.)
* Abandons solid white optimizations for the sake of simplicity
(screen was the only mode that previous had solid white opts).
Minor differences:
* Inconsequential differences in opt flags (e.g. we now return
kCanTweakAlphaForCoverage_OptFlag even when there is no coverage).
* Src coeffs when the shader outputs 0.
* IS2C vs IS2A when the secondary output is scalar.

This CL is ugly but it:
removes the stored SkGpuDevice back pointer from GrTextContext (at the cost of passing more parameters)
moves SkGpuDevice::internalDrawPath to GrDrawContext::drawPathFull
Unfortunately, the GrTextContext-derived classes still need the SkGpuDevice for filterTextFlags calls but I will try removing that in a separate CL.

Make GrResourceCache performance less sensitive to key length change.
The memcmp in GrResourceKey is called when SkTDynamicHash jumps the
slots to find the hash by a index. Avoid most of the memcmps by
comparing the hash first.
This is important because small changes in key data length can cause
big performance regressions. The theory is that key length change causes
different hash values. These hash values might trigger memcmps that
originally weren't there, causing the regression.
Adds few specialized benches to grresourcecache_add to test different
key lengths. The tests are run only on release, because on debug the
SkTDynamicHash validation takes too long, and adding many such delays
to development test runs would be unproductive. On release the tests
are quite fast.
Effect of this patch to the added tests on amd64:
grresourcecache_find_10 738us -> 768us 1.04x
grresourcecache_find_2 472us -> 476us 1.01x
grresourcecache_find_25 841us -> 845us 1x
grresourcecache_find_4 565us -> 531us 0.94x

grresourcecache_find_5 834us -> 749us 0.9x
grresourcecache_find_3 620us -> 542us 0.87x

grresourcecache_add_54 3.34ms -> 2.62ms 0.78x
grresourcecache_add_5 2.68ms -> 2.1ms 0.78x
grresourcecache_add_10 2.7ms -> 2.11ms 0.78x
grresourcecache_add_2 1.85ms -> 1.41ms 0.76x
grresourcecache_add 1.84ms -> 1.4ms 0.76x
grresourcecache_add_4 1.99ms -> 1.49ms 0.75x
grresourcecache_add_3 2.11ms -> 1.55ms 0.73x
grresourcecache_add_55 39ms -> 13.9ms 0.36x
grresourcecache_find_55 23.2ms -> 6.21ms 0.27x
On arm64 the results are similar.
On arm_v7_neon, the results lack the discontinuity at 55:
grresourcecache_add 4.06ms -> 4.26ms 1.05x
grresourcecache_add_2 4.05ms -> 4.23ms 1.05x
grresourcecache_find 1.28ms -> 1.3ms 1.02x
grresourcecache_find_56 3.35ms -> 3.32ms 0.99x
grresourcecache_find_2 1.31ms -> 1.29ms 0.99x
grresourcecache_find_54 3.28ms -> 3.24ms 0.99x
grresourcecache_add_5 6.38ms -> 6.26ms 0.98x
grresourcecache_add_55 8.44ms -> 8.24ms 0.98x
grresourcecache_add_25 7.03ms -> 6.86ms 0.98x
grresourcecache_find_25 2.7ms -> 2.59ms 0.96x
grresourcecache_find_4 1.45ms -> 1.38ms 0.95x
grresourcecache_find_10 2.52ms -> 2.39ms 0.95x
grresourcecache_find_55 3.54ms -> 3.33ms 0.94x
grresourcecache_find_5 2.5ms -> 2.32ms 0.93x
grresourcecache_find_3 1.57ms -> 1.43ms 0.91x
The extremely slow case, 55, is postulated to be due to the index jump
collisions running the memcmp. This is not visible on arm_v7_neon probably due
to hash function producing different results for 32 bit architectures.
This change is needed for extending path cache key in Gr
NV_path_rendering codepath. Extending is needed in order to add dashed
paths to the path cache.

Make the code more readable by inheriting GrStrokeInfo from SkStrokeRec.
This should avoid the long .getStrokeRec() and .getStrokeRecPtr(). These
were a bit cumbersome especially in cases where an alias variable was
created for these, and then the reader had to keep track to which
StrokeInfo member the StrokeRec alias was pointing.
Removes SkStrokeRec::SkStrokeRec(const SkStrokeRec&). It was memcpying.
Try to play it safe wrt compiler using the possible padding of
superclass for subclass members. Instead, let the compiler generate
the copy constructor. Assignment operator was already
compiler-generated, so at least in that way this is consistent.
Renames GrStrokeInfo::applyDash to applyDashToPath for consistency
with superclass applyToPath.

Adds small pictures for drawRect(), drawTextBlob(), and drawPath().
These cover about 89% of draw calls from Blink SKPs,
and about 25% of draw calls from our GMs.
SkPicture handles:
- serialization and deserialization
- unique IDs
Everything else is left to the subclasses:
- playback(), cullRect()
- hasBitmap(), hasText(), suitableForGPU(), etc.
- LayerInfo / AccelData if applicable.
The time to record a 1-op picture improves a good chunk
(2 mallocs to 1), and the time to record a 0-op picture
greatly improves (2 mallocs to none):
picture_overhead_draw: 450ns -> 350ns
picture_overhead_nodraw: 300ns -> 90ns

This CL refactors the location of the GrBufferAllocPools so they reside entirely inside the GrBatchTarget. This is in preparation for making them use scratch resources.

Motivation: PDF/A metadata will need the creation date embedded in it.
Also, GetDateTime returns local time in Win32. This now behaves the
same as on Unix systems.

Updates GrXferProcessor to read directly from the RT texture when
texture barriers are supported and it needs to know the dst color.
Also adds the notion of an Xfer barrier and uses it to issue texture
barriers when the XP will read the RT.

A helper function is privately added to SkPath.h to permit a test to modify a given point in a path.

Must have been we needed them to be weird (mutable, const setter) before.
It doesn't look like that's necessary now... we can just pass it to the
constructor.

The pointer of reference is always not-null. It causes >50k lines of warnning when chromium is compiled by clang.
Warning looks like

Effectively all this does is future-proof any GLSL-specific code, as
GLSLCaps is just a typedef of GLCaps.

Also strips SK_SUPPORT_LEGACY_COLOR32_MATH,
which is no longer needed.
Seems handy to have SkTypes include the relevant intrinsics when
we know we've got them, but I'm not married to it.
Locally this looks like a pointlessly small perf win, but I'm mostly

This may be a small help to slimming paint:
picture_overhead_draw 1.25us -> 1.22us 0.98x
picture_overhead_nodraw 318ns -> 276ns 0.87x
It certainly cannot hurt performance.

This saves "up to" 22 bytes per SkPicture.
Due to alignment, this reduces sizeof(SkPicture):
- from 88 to 72 bytes on Linux x64
- from 68 to 48 bytes on Android
(with Chrome's build settings)
It also somewhat simplifies the GPU veto logic.

Move line dashing logic from GrContext::drawPath to
GrDashLinePathRenderer. This makes it possible to let path renderers render arbitrary dashed paths.
End goal is to implement dashing in GrStencilAndCoverPathRenderer.

Adds an onGetBlendInfo method for GrXferProcessor subclasses to
override instead of overriding getBlendInfo directly. This gives the
base class a chance to initialize the struct with default values
before passing it on. As the BlendInfo struct grows, this will keep
things simple and less error prone.

Chrome wants to call this more often, and it's quite slow today.
Seems like this could be clearer if SkPictureUtils::ApproxBytesUsed() were SkPicture::approxBytesUsed().

SkFixedToDouble uses the decimal floating point string representation
of 1/(2^16) to provide a constant value. This value is exactly
representable by a double but the decimal constant currently used
does not map to this value.
This change modifies this constant to more decimal digits so that
the actual double value desired is created.

Currently there exist SkScalarPin and SkPin32, and in a future change
another version is desired. This change introduces SkTPin and changes
SkScalarPin and SkPin32 to use it.

The benches for N <= 10 get around 2x faster on my N7 and N9. I believe this
is because of the reduced function-call-then-function-pointer-call overhead on
the N7, and additionally because it seems autovectorization beats our NEON code
for small N on the N9.
My desktop is unchanged, though that's probably because N=10 lies well within a
region where memset's performance is essentially constant: N=100 takes only
about 2x as long as N=1 and N=10, which perform nearly identically.

Instead of using a full-blown SkPaint to store run font info, use a
custom structure.
This saves 96 bytes / run on 64bit platforms.
