not designed for external use. In addition to reducing the external
support burden, this will allow Skia to freely refactor this file.

Currently, SkPaintFilterCanvas does not provide any help in cloning
target canvas state. While that could be handled in subclasses, it is
easy to miss (see linked bug).
This CL adds a new constructor variant which ensures that the initial
matrix and clip bounds are inherited from the target canvas.

This CL starts the process of pushing kLegacyFontHost_InitType-type SkSurfaceProps up the call stack and out of Skia. It:
Gets rid of the default SkBaseDevice ctor. This means everyone has to always hand an explicit SkSurfaceProps to it.
It makes public the SkBitmapDevice creation methods that require SkSurfaceProps.
Removes (in Skia's code base) all SkBitmapDevice ctor calls w/o SkSurfaceProps.
Makes the "recording" canvases (e.g., pdf, svg, xps) explicitly not use kLegacyFontHost_InitType.
Replicates the creating canvas/device's flags on saveLayer devices

SkStream is a stateful object, so it does not make sense for it to have
multiple owners. Make SkStream inherit directly from SkNoncopyable.
Update methods which previously called SkStream::ref() (e.g.
SkImageDecoder::buildTileIndex() and SkFrontBufferedStream::Create(),
which required the existing owners to call SkStream::unref()) to take
ownership of their SkStream parameters and delete when done (including
on failure).
Switch all SkAutoTUnref<SkStream>s to SkAutoTDelete<SkStream>s. In some
cases this means heap allocating streams that were previously stack
allocated.
Respect ownership rules of SkTypeface::CreateFromStream() and
SkImageDecoder::buildTileIndex().
Update the comments for exceptional methods which do not affect the
ownership of their SkStream parameters (e.g.
SkPicture::CreateFromStream() and SkTypeface::Deserialize()) to be
explicit about ownership.
Remove test_stream_life, which tested that buildTileIndex() behaved
correctly when SkStream was a ref counted object. The test does not
make sense now that it is not.
In SkPDFStream, remove the SkMemoryStream member. Instead of using it,
create a new SkMemoryStream to pass to fDataStream (which is now an
SkAutoTDelete).
Make other pdf rasterizers behave like SkPDFDocumentToBitmap.
SkPDFDocumentToBitmap delete the SkStream, so do the same in the
following pdf rasterizers:

blink skips all pending commands during picture recording if it is drawing an opaque full-frame

The base class, SkCanvasState, now holds the version, width, and
height. These fields will always be a necessary part of the class.
(Also add in some padding.)
The other fields, which may change, have been moved into the
subclass, SkCanvasState_v1. If/when the version changes, it will
correspond to a new subclass.
In SkCanvasStateUtils::CreateFromCanvasState, check the version on
the base class, then do a static_cast to the version corresponding
to SkCanvasState::version.
Remove CANVAS_STATE_VERSION, which is redundant with the version
specified by the subclass.

This splits the playback functionality out of SkPictureData. The old SkPictureData::draw method is pulled out along

re-enable profiling in the debugger (and remove the vestiges of SkTimedPicture)
re-enable display of command offsets in the picture (this should probably wait until we've switched to SkRecord though)

Like yesterday's change to run CPU-parent child tasks serially in thread, this
reduces peak memory usage by improving the temporaly locality of the bitmaps we
create.
E.g. Let's say we start with tasks A B C and D
Queue: [ A B C D ]
Running A creates A' and A", which depend on a bitmap created by A.
Queue: [ B C D A' A" * ]
That bitmap now needs sit around in RAM while B C and D run pointlessly and can
only be destroyed at *. If instead we do this and push dependent child tasks
to the front of the queue, the queue and bitmap lifetime looks like this:
Queue: [ A' A" * B C D ]
This is much, much worse in practice because the queue is often several thousand
tasks long. 100s of megs of bitmaps can pile up for 10s of seconds pointlessly.
To make this work we add addNext() to SkThreadPool and its cousin DMTaskRunner.
I also took the opportunity to swap head and tail in the threadpool
implementation so it matches the comments and intuition better: we always pop
the head, add() puts it at the tail, addNext() at the head.

The main meat of things is in SkThreadPool. We can now give SkThreadPool a
type for each thread to create and destroy on its local stack. It's TLS
without going through SkTLS.
I've split the DM tasks into CpuTasks that run on threads with no TLS, and
GpuTasks that run on threads with a thread local GrContextFactory.
The old CpuTask and GpuTask have been renamed to CpuGMTask and GpuGMTask.
Upshot: default run of out/Debug/dm goes from ~45 seconds to ~20 seconds.

*** 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.
