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.

Revert "Revert "PixelRef now returns (nearly) everything that is currently in SkBitmap. The goal is to refactor bitmap later to remove redundancy, and more interestingly, remove the chance for a disconnect between the actual (pixelref) rowbytes and config, and the one claimed by the bitmap.""""""
This reverts commit eabd6b2ed4e494b323c08f32358f45950a0368c3.

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.

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.

unused headers and fixes a couple of bugs exposed by changing the random
number generator:
First, the function SkMatrix::getMaxStretch() had an error where it was testing
the square of a number against near-zero. This led to it occasionally taking a
cheaper but imprecise path for computing the eigenvalues of the matrix. It's
been replaced with a check against the square of SK_ScalarNearlyZero.
The second case was a failure in ClipStackTest, where it hit the rare case of
a practically empty clip stack (it has a single Union) and we set a tight
bounds. The bounds rect doesn't get set by GrReducedClip::ReduceClipStack() in
this case, so when it clips the reduced stack it's clipping against garbage,
and the resulting regions don't match. The solution is to initialize the
tightBounds rect.

I removed unused parameters in the tests wherever it was trivial to do so. I'm trying to get the easy ones out of the way before we get into more involved discussions around this.
