Fixed a few issues while attempting to use the new
serialization path for SkPicture inside a fuzzer:
- SkReadBuffer and SkValidatingReadBuffer both had a fReader
member instead of sharing the same member, which leads to
problems if a base class function is used
- In SkPicture, a header is now written as a single chunk of
data, so it also has to be read as a single chunk of data
- In the SkPicturePlayback destructor, a bad deserialization
would lead to a crash if we don't safely unref fOpData
- Also in SkPicturePlayback, if we only use a ReadBuffer for
the whole deserialization, additional tags must be added to
parseBufferTag()
- SkValidatingReadBuffer::readBitmap() was broken, but this
path wasn't usen't since the only use case for
SkValidatingReadBuffer is currently image filters and
bitmaps are unflattened as part of the deserialization of
SkBitmapSource
- SkPictureImageFilter was not deserializable. Added it to
SkGlobalInitialization*
- Added a test that exercises the SkPicture serialization /
deserialization code

*** SKP format breaking change ***
Adding a couple of culling primitives: pushCull(SkRect) & popCull().
These are currently only plumbed for SKP playback quickreject.
At record time, we perform a couple of optimizations to trim down the
number of redundant culls:
* collapse empty pushCull/popCull pairs
* skip pushCull/popCull pairs nested within an identical cull rect
Things still missing/to consider:
* use an inlineable, simplified quickreject (Mike's old prototype)
* debugger visualization for cull boxes
* BBH integration: the initial prototype had some minimal BBH support,
but since the optimizations required expensive rewinds and culling
is expected to be a BBH alternative, it got dropped.

Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.
What used to be this:
SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer
is now
SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer
Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed
This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.

There's little benefit to deduping matrices and regions: they're infrequently
used, and doubly infrequently reused. Their use-weighted byte cost is tiny.
There is some downside to deduping matrices and regions. Even when they're not
used, we prepare dictionaries for deduping them for every picture. Each of
these dictionaries costs 160 bytes, so two unused dictionaries make a big chunk
of the ~1100 bytes it takes to allocate an SkPictureRecord. (~330 come from
parent class SkCanvas, 768 from SkPictureRecord itself, here reduced to 448).
One side benefit of not deduping these guys is that the change weighs -140 lines of code.
It may go without saying, but this breaks the picture format.

This returns true if (1) the picture has finished recording and
(2) this picture or any picture drawn into it refers to any bitmaps.
It allows clients doing complicated manipulations of the picture to
early-out when there are no bitmaps present.

SkPicture:
Remove the constructors which take an SkStream as an argument. Rather
than having to check a variable for success, the factory will return
NULL on failure.
Add a protected function for determining if an SkStream is an SKP
to share code with SkTimedPicture.
In the factory, check for a NULL SkStream.
Use a default decoder (from BUG:
https://code.google.com/p/skia/issues/detail?id=1325)
SkDebuggerGUI:
Call SkPicture::CreateFromStream when necessary.
Write a factory for creating SkTimedPictures and use it.
Use the factory throughout tools.
Add include/lazy to utils and effects gyp include_dirs so SkPicture.h
can reference SkImageDecoder.h which references SkBitmapFactory.h (in
include/lazy).
Changes code Chromium uses, so this will require a temporary Skia
and then a change to Chromium to use the new Skia code.
TODO: Create a decoder that does nothing to be used by pinspect,
lua pictures, etc, and allow it to not assert in SkOrderedReadBuffer.

This change gives more flexibility to the implementation of
EncodeBitmap to prefer calling refEncodedData, doing its own
encode, or even doing both and making a decision about which
to use.
The new function signature also allows the implementation to
tell the ordered write buffer whether to store the pixel offset,
in the case where the encoded bitmap represents the larger
bitmap, or to ignore the pixel offset, in the case where the
implementation only encoded the subset that is used.
Requires changes to chromium to use the new function signature.
(https://codereview.chromium.org/15496006/)
SkPicture:
New API for EncodeBitmap.
SkOrderedReadBuffer:
Ifdef'd out addition of reading the offset.
SkOrderedWriteBuffer:
Never call refEncodedData. Allow the user to call that from their
EncodeBitmap function, if desired.
This addresses https://code.google.com/p/skia/issues/detail?id=1239
Add in ifdef'd out code to record the offset.
PictureTest and PictureRenderer:
Implement the new definition of EncodeBitmap. Also update the name
of the function to meet coding style guidelines.

Similar goals as https://codereview.chromium.org/14437012.
Builds on patch set 1 from that issue
(https://codereview.chromium.org/14437012/#ps1).
Instead of the changes in patch set 2 from that issue, this
changes SkOrderedWriteBuffer::writeBitmap to store whether an
SkBitmapHeap was used when to store the index of the SkBitmap.
SkOrderedReadBuffer::readBitmap now uses that information to
distinguish between using the heap and unflattening.
In addition, writeBitmap now records the width/height first in
all cases. If now SkBitmapHeapReader is attached, but an
SkBitmapHeap was used to record the bitmap, reading will fail
and provide the same red SkBitmap as in the case where the
SkBitmap was encoded but could not be decoded.
Updates the PICTURE_VERSION as well.
The key differences in this CL to look at are in:
SkOrderedWriteBuffer,
SkOrderedReadBuffer,
and SkPicture.

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.

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.

The CL adds SkPicture.clone() which produces a thread-safe copy by
creating a shallow copy of the thread-safe data within the picture and
a deep copy of the data that is not (e.g. SkPaint). This implementation
re-flattens the paints when cloning instead of retaining the flattened
paints from the recording process.
Changes were also needed to various classes to ensure thread safety

Prior to this CL mutable bitmaps only saved a copy of their pixels
if a flag was set at recording time. That flag has been removed
and the default behavior when recording a mutable bitmap is to
make a copy of it's pixels. This is the only way to ensure that
the pixels are not manipulated before we playback their contents.
However, enabling this behavior breaks the recording of extracted
bitmaps in SkPicture. This is because we currently cache bitmaps
within a picture based only on their pixelRef. This results in
false positive cache hit when drawing an extracted bitmap as it
shares a pixelRef with its orginating bitmap. Therefore we must
update the index of the bitmap cache to be both the pixelRef AND
the size and offset of the bitmap using those pixels.
