SkNVRefCnt is a variant of SkRefCnt that's Not Virtual, so weighs 4 bytes
instead of 8 or 16. There's only benefit to doing this if the deriving class
does not otherwise need a vtable, e.g. SkPicture.
I've stripped out some cruft from SkPicture, rearranged fields to pack tightly,
and added compile asserts for the sizes of SkPicture, SkRecord, and
SkVarAlloc.

Idea:
1. in its mutable recording state, keep a table of drawables on the side, and store an index in the record list.
2. In "immediate-mode" draw, just call the clients drawable directly (need access to our private list to turn the stored index into a proc)
3. when we "snap", we replace the list of drawables with a list of (sub) pictures, and then during playback of the snapped picture, we invoke a private drawable which just calls "drawPicture" on the index'd subpicture.

Under the hood, add SkPixelGeometry to the CreateInfo for new devices, allowing them to see their geometry (SkDeviceProperties) up front, rather than having it changed later.
The only exception is for devices that are used on the root-layer, where we don't see the device until after the fact (at least as long as we allow clients to attach a device to a canvas externally).
We also filter the geometry when we're creating a layer, so we can disable LCD text automatically if the layer is not marked as opaque.

The FillBounds and CollectLayers code has diverged significantly resulting in the rendering path seeing different bounds than the hoisting path. This CL merges the FillBounds changes into CollectLayers. A follow on CL will, hopefully, find a way to layer CollectLayers on top of FillBounds.

Add a new enum to differentiate between a complete decode and a
partial decode (with the third value being failure). Return this
value from SkImageDecoder::onDecode (in all subclasses, plus
SkImageDecoder_empty) and ::decode.
For convenience, if the enum is treated as a boolean, success and
partial success are both considered true.
Note that the static helper functions (DecodeFile etc) still return
true and false (for one thing, this allows us to continue to use
SkImageDecoder::DecodeMemory as an SkPicture::InstallPixelRefProc in
SkPicture::CreateFromStream).
Also correctly report failure in SkASTCImageDecoder::onDecode when

Currently, the PDF backend does not support image filters (since PDF
does not have that functionality), so it simply removes them. This is
causing Chrome print preview to render incorrectly (see bug). The fix
here is to fall back to a raster device for image filters, as we used
to do in Blink. The resulting bitmap will be drawn to the destination
device as a normal main-memory-backed bitmap.
Note: this change invalidates the PDF results of all GMs containing
image filters (since they'll actually be rendered).

A careful reading of the preprocessor specification indicates that
any use of the 'defined' operator outside the form of 'defined X' or
'defined ( X )' directly in the constant expression of a '#if' or
'#elif' may cause undefined behavior.
In particular, msvc is very unpredictable. The 'defined X' and
'defined ( X )' forms behave differently when created from marco
expansion, with 'defined ( X )' generally evaluating to '0L'. The
'defined X' form generally behaves more the way one would expect,
but still has a number of quirks which should simply be considered
undefined behavior.

Before getting too far into changing how SkTileGrid stores its tiles, I figured I'd
better see how much I can tweak out the existing format. Cleverly, that way
any improvements I make by changing the format will look that much less
impressive.
This CL looks like it will be a 5-15% win in time spent recording, with no effect
on playback.
This CL also shrinks the tiles to fit exactly when we're done inserting,
using newly added SkTDArray::shrinkToFit(). It's quite cheap to run (maybe
taking back 1-2% from those 5-15% wins), and means we'll lug around about 15%
fewer bytes in the tile grids. Note though this strategy temporarily uses up to
30% more memory while building the tile grid. For our largest SKPs, that's
maybe 75-100K extra.

Having hoisted layers from different pictures invalidates the assumptions of the old GrReplacements object. This is fixed by switching to a SkTDynamicHash-based back-end.
Sub-picture-layers also require that the replacement drawing occur for the sub-pictures too. The ReplaceDraw object is added to make this happen and limit the replacement lookup to saveLayer draw commands.

Feature-wise, this removes:

2) peephole optimizations;
3) record-time text op specializations;
4) the guarantee that SkPaints are flattened.
This deletes the optimizations GM, which only exists to test the peepholes of
the old backend. SkRecord optimizations are unit tested, and if that ever fails we
can think about adding another GM like this, but they're different enough we'd
want to start from scratch anyway.
We need to keep the code that plays back the specialized text ops around for
a while for compatibility with existing .SKPs that have those ops recorded.

Implement proper x/y drawTextBlob() handling by plumbing a
drawPosText() offset parameter (to act as an additional glyph pos
translation) throughout the device layer.
The new offset superceeds the existing constY, with a minor semantic
tweak: whereas previous implementations were ignoring constY in 2D
positioning mode (scalarsPerGlyph == 2), now the offset is always
observed, in all positioning modes. We can do this because existing
drawPosText() clients always pass constY == 0 for full positioning mode.

fDirtyBits is only used by SkPaint::FlatteningTraits, which in turn was
only used as a smaller, faster format to flatten paints in-memory to dedup
them in the old picture backend.
SkRecord obsoleted all this. Neither flatten()/unflatten() (disk format)
nor FlatteningTraits is used anywhere performance or size matters.
Here I revert the deduping code back to using the disk format for flattened paints.
We stil do have to flatten and unflatten paints while coverting from SkRecord
backend to the old backend, so we can't just delete this all yet, but any
faithful round trip flatten()/unflatten() pair will be fine, however slow.

Refactored text blob backend for improved performance: instead of using
separate buffers for runs/positions/glyphs, everything is now packed in
a consolidated slab (including the SkTextBlob object itself!).
Benefits:
* number of allocations per blob construction reduced from ~4 to 1
(also minimizes internal fragmentation)
* run record size reduced by 8 bytes
This takes the blob construction overhead down to negligible levels
(for the current Blink uncached textblob implementation).
Unfortunately, the code is much more finicky (run merging in
particular) -- hence the assert spree.
Multi-run blobs are vulnerable to realloc storms but this is not a
problem at the moment because Blink is using one-run blobs 99% of the
time. Will be addressed in the future.
