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.

There are some cases (like drawing a completely transparent image) where the code tries to finish a content entry with no content and an xfermode other than clear. This makes those cases work correctly.
This is likely what was happening in chromium:316546, but it wasn't clear what the core problem was. desk_techcrunch.skp tripped a debug only assert that exposed the core issue.

Adds "grresourcecache_add" and "grresourcecache_find" bench tests to test
GrResourceCache::add and GrResourceCache::find. The tests work only
with GPU backends, since GrResourceCache needs an GrGpu.
Modifies bench tests to override SkBenchmark::isSuitableFor(Backend)
function that specifies what kind of backend the test is inteded
for. This replaces the previous "fIsRendering" flag that would
indicate test that did no rendering.
Adds SkCanvas::getGrContext() call to get the GrContext that the
canvas ends up drawing to. The member function solves a common
use-case that is also used in the benchmark added here.
