Skia cannot use Chromium's implementation of mutex (Lock) due to static
initializers. However, we would like to be able to use Chromium's
implementation of atomics. This motivates the split of implementation.
Skia's atomic and mutex calls should be inlinable, especially the atomics.
These calls often compile down to very few instructions, and we currently have
the overhead of a function call. This motivates the header implementation.
There is still a desire for the build system to select the implementation, so
the SK_XXX_PLATFORM_H pattern for header files is introduced. This allows the
build system to control which platform specific header files are chosen.

- Implement ashmem-backed SkDiscardableMemory subclass:
This class in only accesible via the SkDiscardableMemory::Create()
function, which replaces the mock implementation in
SkDiscardableMemory_none.cpp
- Added SkDiscardableMemory_ashmem.cpp to the Android port of Skia
Removed SkDiscardableMemory_none.cpp from the Android port.
- Added DiscardableMemoryTest.
Still needs work.
- SkDiscardablePixelRef Bugfix:
onLockPixels() now calls SkDELETE on the SkDiscardableMemory pointer
when it fails to unlock.
- Improved documentation inside ashmem.h

DM writes out its images in a hierarchy that's a little different than GM,
so this can't read GM's output. But it can read its own, written with -w.
Example usage:
$ out/Release/dm -w /tmp/baseline
$ out/Release/dm -r /tmp/baseline -w /tmp/new
(and optionally)
$ mkdir /tmp/diff; out/Release/skdiff /tmp/baseline /tmp/new /tmp/diff
GM's IndividualImageExpectationsSource and Expectations are a little too eager
about decoding and hashing the expected images, so I took the opportunity to
add DM::Expectations that mostly replaces skiagm::ExpectationsSource and
skiagm::Expectations in DM. It mainly exists to move the image decoding and
comparison off the main thread, which would otherwise be a major speed
bottleneck.
I tried to use skiagm code where possible. One notable place where I differed
is in this new feature. When -r is a directory of images, DM does no hashing.
It considerably faster to read the expected file into an SkBitmap and do a
byte-for-byte comparison than to hash the two bitmaps and check those.
The example usage above isn't quite working 100% yet. Expectations on some GMs
fail, even with no binary change. I haven't pinned down whether this is due to
- a bug in DM
- flaky GMs
- unthreadsafe GMs
- flaky image decoding
- unthreadsafe image decoding
- something else
but I intend to. Leon, Derek and I have suspected PNG decoding isn't
threadsafe, but are as yet unable to prove it.
I also seem to be able to cause malloc to fail on my laptop if I run too many
configs at once, though I never seem to be using more than ~1G of RAM. Will
track that down too.

This also includes some changes to the xfermodeimagefilter and tileimagefilter GMs to properly handle the CTM. This worked before only because SkBitmapSource was ignoring the CTM. Now that it respects it, we need to give the correct transform. This also means the GMs now work while zoomed. It also implements CTM support for SkTileImageFilter.
NOTE: this will require rebaselining a number of imagefilter GMs on Nexus4, since they render in perspective (using the CTM). The changes to the results should all be improvements.

Note: I initially implemented this as a fully-generic SkResizeImageFilter, but then I realized that the dstRect should always be transformed by the filter matrix, but that the srcRect should not (since it's specified relative to the dimensions of the original bitmap). Since this would be confusing for someone attempting to use this as a generic resizing filter, I decided to build the functionality into SkBitmapSource instead.

Removed SkBitmapFactory since no clients were using it. New cache
selection mechanism can simply pass a SkDiscardableMemory::Factory
into the SkDiscardablePixelRef if non-default SkDiscardableMemory
should be used. Removed BitmapFactoryTest.
SkDiscardableMemory::Factory interface. Android will need this
functionality in the future inside their BitmapFactory.
Removed SkLazyPixelRef, since it's functionality is now subsumed into
SkDiscardablePixelRef. Removed LazyPixelRef test.
Modified SkDiscardablePixelRef to optionally allow it to use a
SkDiscardableMemory::Factory. This tiny change makes it a replacement
for SkLazyPixelRef. This functioanlity is also necessary for moving
Android over to SkDiscardablePixelRef from SkImageRef in a later CL.
Added a test for this.
SkDecodingImageGenerator::Install can optionally pass a factory in to
SkDiscardablePixelRef.
Removed SkImageCache, SkLruImageCache, and SkPurgeableImageCache.
This functionality can be handled much more cleanly by
SkDiscardableMemory.
New SkDiscardableMemoryPool class to replace SkLruImageCache. In a
later CL, we will replace SkImageRef_GlobalPool (used by android) as
well. This is a concrete implementation of
SkDiscardableMemory::Factory. Added a test for this.
modified gm/factory.cpp to remove dependnce on SkBitmapFactory +
SkLruImageCache. Now uses SkDecodingImageGenerator +
SkDiscardablePixelRef + SkDiscardableMemoryPool.
SkImageDecoder::Target replaces SkBitmapFactory::Target. The
DecodeMemoryToTarget function may disappear in the future.
Moved SkLazyCachingPixelRef::DecodeProc replaces
SkBitmapFactory::DecodeProc. This is a short term change, since
another CL changes SkLazyCachingPixelRef to use SkImageGenerator
instead of DecodeProc.
Modified DrawBitmapRectTest to use SkDiscardablePixelRef instead of
SkLazyPixelRef.
tools/LazyDecodeBitmap.cpp now uses SkDecodingImageGenerator +
SkDiscardablePixelRef instead of a SkBitmapFactory.
bench_pictures uses the Global SkDiscardableMemoryPool instead of a
global gLruImageCache.

Add INHERITED declarations to class declarations that prevent
compilation with the flag.
Remove SK_DEFINE_INST_COUNT from all class implementations. Instead,
use function-local static variables in the reference count helper
classes to create the global instances to store the needed info. The
accessor functions are defined inline in the helper classes, so
definitions are not needed. The initialization point of the variables
should be as well defined as previously.
Remove SK_DECLARE_INST_COUNT_TEMPLATE and use SK_DECLARE_INST_COUNT
instead. This avoids possible future compilation errors further.
For SK_ENABLE_INST_COUNT=0 compilation, add an empty static member
function to all classes that use SK_DECLARE_INST_COUNT and
SK_DECLARE_INST_COUNT_ROOT macros. The function ensures that classes
contain public INHERITED typedef. This member function seems to be
compiled away. This shouĺd ensure that part of the compilation errors
are caught earlier.
Also adds DSK_DECLARE_INST_COUNT to few SkPDFDict subclasses.

Move its functionality out of readToken() and into its own class.
Callers of the previous readToken() now call
SkPdfNativeTokenizer::readToken(), which in turn calls a function
for writing the diff to a file, if the caller requests it and
PDF_TRACE_DIFF_IN_PNG is defined.
Do not attempt to draw a diff for compatibility sections, which we
do not draw.
Use SkString to handle string manipulation.
Hide globals only used by PDF_TRACE_DIFF_IN_PNG behind that flag.
Remove hasVisualEffects, which always returns true.
Rename gLastOpKeyword to gOpCounter for clarity.
In SkPdfNativeTokenizer, set fEmpty to true when the entire stream
has been read.
Use SkBitmap::copyTo instead of manually copying an SkBitmap.

The only change in behavior is that SkPdfAllocator on SkPdfContext is
no longer allocated on the heap.
In general, I have just moved code.
SkPdfContext:
Inherit from SkNoncopyable.
Make SkPdfContext directly own fTmpPageAllocator. fTmpPageAllocator is
created when SkPdfContext is, and destroyed at the same time as well,
so there is no reason for the extra allocation.
Add the function parseStream. This eliminates code duplication, and
allows making fTmpPageAllocator private.
Move PdfMainLooper into the implementation file, since it is now only
used by parseStream.
Move SkTDictWithDefaultConstructor and render stats info here, in
support of PdfMainLooper.
SkPdfTokenLooper:
Rename PdfTokenLooper to SkPdfTokenLooper.
Move readToken here, unchanged.
Remove tokenizer(), which is unused.
SkPdfNativeDoc:
Remove tokenizerOfPage and tokenizerOfBuffer, which are unused.
SkPdfOps:
Move gPdfOps and PdfOperatorRenderer into a header file (hidden for
now), so they can be accessed by both SkPdfRenderer.cpp and
SkPdfContext.cpp.
SkPdfRenderer:
Harvest things into other files:
PdfMainLooper (and the code that calls it) -> SkPdfContext.
readToken -> SkPdfTokenLooper.

The following have the same effect on Windows:
'msvs_settings': { 'VCLinkerTool': { 'AdditionalDependencies': [ 'windowscodecs.lib', ],},},
'link_settings': {'libraries': ['-lwindowscodecs.lib',],},
But this one is different:
'link_settings': {'libraries': ['windowscodecs.lib',],},
since this last one will attempt to find the library at
third_party\skia\gyp\windowscodecs.lib
or a place like this, instead of looking in the library paths.
This also fixes capitalization of the affected libraries.

The GCC compilers for Android and Ubuntu do not seem to be able to
inline the memcmp operations on GrBinHashKey data. Write the comparisons
manually. Also shortcut GrBinHashKey::EQ to skip comparison when hashes
do not match.
Speeds up grresourcecache_find test on ARM and x86_64. Speeds up
grresourcecache_add on x86_64.
In order to test the change, moves ad hoc Gr unit tests from
src/gr_unittest.cpp to tests/GrUnitTests to be consistent with other
tests and enables GrUnitTests.
Fixes a regression from r2863 with where re-setting GrBinHashKey data
would not set the hash correctly. This should also improve the hash
function itself. The regression caused many of the hash operations be
no-ops. This is caught by the unit test.
Renames the comparison functions that GrHashTable needs from EQ, LT to
Equals, LessThan.
Renames GrTBinHashKey to GrBinHashKey. The GrTBinHashKey used to
forward comparison functions to an ENTRY template class, which would
extract the key and call back to the GrTBinHashKey. This would save
the user from writing one comparison function when comparison was done
with int ENTRY::compare(). There's no real benefit in this now. Also
this was used only for one class (GrTextureStripAtlas). The other use
in GrResourceKey was not actually using the provided "shortcut". The
new GrBinHashKey is not templated with the entry, rather just provides
== and < functions. The users of GrTHashTable provide the needed
functions now.
Adds explicit documentation of functions that are actually needed
GrTHashTable for the Key template. Adds SK_DEBUG guards according to
the contract.
