d665dc4c10 Add Options to SkDecodingImageGenerator, simplify API.
Motivation: We want to remove redundant classes from Skia.  To
that end we want to remove SkImageRef and its subclasses and
replace their uses with SkDiscardablePixelRef +
SkDecodingImageGenerator.  Since Android uses SkImageRef, we need
to make sure that SkDecodingImageGenerator allows all of the
settings that Android exposes in BitmapFactory.Options.

To that end, we have created an Options struct for the
SkDecodingImageGenerator which lets the client of the generator set
sample size, dithering, and bitmap config.

We have made the SkDecodingImageGenerator constructor private
and replaced the SkDecodingImageGenerator::Install functions
with a SkDecodingImageGenerator::Create functions (one for
SkData and one for SkStream) which now take a
SkDecodingImageGenerator::Options struct.

Also added a ImageDecoderOptions test which loops through a list
of sets of options and tries them on a set of 5 small encoded
images.

Also updated several users of SkDecodingImageGenerator::Install to
follow new call signature - gm/factory.cpp, LazyDecodeBitmap.cpp,
and PictureTest.cpp, CachedDecodingPixelRefTest.cpp.

We also added a new ImprovedBitmapFactory Test which simulates the
exact function that Android will need to modify to use this,
installPixelRef() in BitmapFactory.

c2e9db30d3 Fixed a few places where uninitialized memory could have been read
Also added early exit in SkImageFilter's constructor to avoid attempting to deserialize all inputs once a bad input has been found. This avoids hanging if a filter pretends to have 1 billion inputs when that's just an error on the number of inputs read by the filter.

2c7c7ee47d Big Cleanup: SkBitmapFactory, SkLazyPixelRef, SkImageCache
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.
