The new pixel ref behaves similarly to SkImageRef, with some key differences:
It does not depend on the images project.
It requires an SkImageCache, which handles allocation and caching of the pixel
memory.
It takes a function signature for decoding which decodes into already allocated
pixel memory rather than into an SkBitmap.
Add two implementations of SkImageCache: SkLruImageCache and SkAshmemImageCache.
Replace SkSerializationHelpers::DecodeBitmap with SkPicture::InstallPixelRefProc,
and update sites that referenced it.
SkBitmapFactory now sets the pixel ref to a new object of the new
class SkLazyPixelRef, provided it has an SkImageCache for caching.
Provide an option to do lazy decodes in render_pictures and bench_pictures.
SkPicture:
Eliminate the default parameters in the constructor.
If a proc for decoding bitmaps is installed, use it to decode any encoded
data in subpictures.
When parsing deserializing subpictures, check for success.
When serializing subpictures, pass the picture's bitmap encoder to the
subpicture's call to serialize.
Update BitmapFactoryTest to test its new behavior.

When timing individual tiles in bench_pictures, keep a timer running
across all repeats, and then take the average. The former method of
timing each iteration separately runs into precision errors on some
platforms.
Running on my Mac Pro with OSX 10.8, the cmsecs for the new method
and the old method are roughly the same when checking the CPU time.
When checking the wall time, the old method often gives me 0ms,
while the new method gives me a larger value. I don't think this
can be entirely attributed to rounding though, since on occasion I
see the old method showing a short time period (.05 - .15ms) while
the new method shows .15ms higher (which is in range for the
difference I'm seeing for other tiles where the old method reports
0ms).
Some other changes:
PictureRenderer::resetState now takes a boolean parameter. If called
with false, it will only do a flush, while if called with true, it
will also call finish.
resetState is now called with true everywhere except in between
iterations of drawing the same tile (when timing individual tiles).
render_pictures_main no longer calls resetState directly, since it
already calls end, which calls resetState.

now we will default to max diff of 256, which means that for now we
report all pixels that are not as expected and we do not error out.
Ideally we will decrease the value of max diff to something that does
not have visual impact, e.g. 10, then we will report small changes with
the intensity under 10, but we will error out for anything larger.

means the tool should return failure or not. For now it is not defined, which
means any failed pixels are still reported to stdout, but the tool does not
return an error, allowing the bots to go green (until we can fix these failures).

1) flag to verify PNGs produced by render_picture that produce the same pixels
as simple renderer.
2) flag to write one single image (in tile we write individual tiles) - this
will help running skdiff also
3) flag to clone the picture before rendering

In TiledPictureRenderer and CopyTilesRenderer, do a postTranslate so
the translate is not affected by the scale factor.
Likewise, use clipRegion for tiled renderer so it will be
unaffected by the scale factor.
Respect the viewport for record, playbackCreation, and pipe renderers.

Builds on https://codereview.appspot.com/6718046/ by mtklein.
Previously, each iteration of drawing a picture started new threads to draw the picture. Since each thread is using thread local storage for the font cache, this means that each iteration had to start with an empty font cache.
The newly added MultiCorePictureRenderer, separated from TiledPictureRenderer, now starts the drawing threads at the beginning of the test using an SkThreadPool, and keeps them alive through all iterations, so the font cache can be reused.
For now, I have removed the pipe version of the threaded renderer.
Updated bench_pictures_main and render_pictures_main to use the new
renderer, and to unref a renderer before early exit.

and deserialization for encoding and decoding bitmaps.
Remove kForceFlattenBitmapPixels_Flag, which is no longer used.
When an SkOrderedReadBuffer needs to read a bitmap, if it does not
have an image decoder, use a dummy bitmap.
In GM, add a tolerance option for color differences, used when
testing picture serialization, so it can assume two images are the
same even though PNG encoding/decoding may have resulted in small
differences.
Create dummy implementations for SkImageDecoder and SkImageEncoder
functions in SkImageDecoder_empty so that a project that does not
want to include the images project it can still build.
Allow ports to build without images project.
In Mac's image encoder, copy 4444 to 8888 before encoding.
Add SkWriter32::reservePad, to provide a pointer to write non 4 byte
aligned data, padded with zeroes.
In bench_ and render_ pictures, pass decode function to SkPicture
creation from a stream.

Since the passed in picture may represent an image which is too large
to be represented on the GPU, never create such a large canvas. Instead,
after drawing to each tile, create a file showing just that tile.

Remove sk_tools::print_msg, since SkBenchLogger is now used instead.
Combine picture_benchmark with bench_pictures, since that is the
