edd370f949 Sk_API for SkImageGenerator and SkInstallDiscardablePixelRef
Added SK_API to SkImageGenerator (already in include/).

Moved SkDiscardablePixelRef::Install to SkInstallDiscardablePixelRef,
added SK_API to that function, and moved declaration to
SkImageGenerator.h

This keeps the SkDiscardablePixelRef internal to Skia, but exposes a
method to install it into a bitmap.

Modifed tests that rely on this functio to use new version.

bc55eec80e Implement SkAshmemDiscardableMemory
-   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

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.

6e3e42296b Break up SkLazyPixelRef functionally into class hierarchy.
The reason for this CL is to allow greater decoder flexibility.
Chrome currently uses its own decoding functions.  These allow for
greater flexibility in dealing with images with multiple frames or
partial data.  The DecodeProc function was not flexible enough to
handle these.  Instead of asking the decoder to squeeze everything
into the DecodeProc, we now ask the downstream library to inherit from
SkCachingPixelRef.  If WebKit's LazyDecodingPixelRef is re-tooled to
inherit from SkCachingPixelRef, then it can make use of Skia's caching
ability while still allowing it to deal with multiple frames, scaling,
subsetting, and partial data.

-   The abstract SkCachingPixelRef class handles caching the decoded
    data in a SkScaledImageCache.  This class relies on the virtual
    functions onDecodeInfo() and onDecode() to do the actual decoding
    of data.

-   The SkLazyCachingPixelRef class is derived from SkCachingPixelRef.
    It provides an implementation of onDecodeInfo() and onDecode() in
    terms of calls to a SkBitmapFactory::DecodeProc function.  It also
    provides an Install() static method which installs a new
    SkLazyCachingPixelRef into a SkBitmap.

SkLazyCachingPixelRef exists for two reasons: to test
SkCachingPixelRef within Skia and as an example for downstream
developers to make their own classes that inherit from
SkCachingPixelRef.

-   The CachedDecodingPixelRefTest was updated to test the
    SkLazyCachingPixelRef class and indirectly the SkCachingPixelRef
    class.

2bd8b81005 move SkImage::ColorType into SkColorType
objective -- move clients over to SkImage

tasks
- use SkImageInfo instead of SkBitmap::Config
- add support for colortables to SkImage
- add drawImage to SkCanvas
- return SkImage from readPixels

This CL works towards the first task

7585479202 Allow SkLazyPixelRef to use SkScaledImageCache
-   SkScaledImageCache:
    -   Add new FindAndLock/AddAndLock variants that work well with
        SkLazyPixelRefs (take width, height, generation_id).
    -   Add static versions of these new variants.

-   SkLazyPixelRef:
    -   If NULL passed in as SkImageCache* in the constructor, it will
        now default to using the static SkScaledImageCache methods to
        cache decoded images.
    -   If (fImageCache==NULL), the default allocator can be changed
        with the setAllocator method.  If (fImageCache!=NULL), the
        SkImageCache handles allocation.

-   CachedDecodingPixelRefTest to test the new functionality.
