b47cd4b3d6 Use SkNVRefCnt for a couple common types. 
These types are ref-counted, but don't otherwise need a vtable.
This makes them good candidates for SkNVRefCnt.

Destruction can be a little more direct, and if nothing else,
sizeof(T) will get a little smaller by dropping the vptr.

2ee6982d95 Sample app uses Ganesh before calling SkGraphics::Init(). 
This causes inconsistent hashing.  Before Init(), we use portable Murmur3,
after a faster SSE4.2-based hash.

To fix, call SkGraphics::Init() first.

8369e32a05 SkLiteRecorder: don't tell SkCanvas about clips 
If no one reads our clip, and we don't expect quickReject() to help,
we can probably get away without maintaining a proper clip stack.

This puts us at about 0.6-0.7x of previous record cost.

0adbd3e0a6 make SpecialLineRec::addSegment assert more permissive to accomodate rounding error 
Because the driving code that calls SpecialLineRec::addSegment uses double precision,
when converted back to single precision this may round such that d0 and d1 are the same.
This causes the assert to trigger. The simplest thing to do here is to modify the assert
to not be so picky and allow the rare/occasional equality.

0446a3c8e2 Add initial CurveMeasure code

- In a future CL we will write a class that uses CurveMeasure to compute dash points. In order to determine whether CurveMeasure or PathMeasure should be faster, we need the dash info (the sum of the on/off intervals and how many there are)

765b6e6548 SkLiteDL: control reuse by a single parameter 
This simply caps the number of times a display list can be reused.
As this number goes up, the average amount of memory we cache goes up
and the expected number of mallocs per SkLiteDL::New() goes down.

This strategy does not need a hard-coded cap on how many display lists
to cache, or how big they can grow.

397a517d1a [SVGDom] Add viewBox support 
The main feature is <svg> viewBox and proper viewport support, but the CL
touches a few other things:

* refactor SkSVGRenderContext to auto-restore canvas state, and split the
  presentation bits into a separate CoW SkSVGPresentationContext

* introduce SkSVGNode::onPrepareToRender(), as a way for nodes to push their
  custom state before the actual onRender() call (instead of relying on
  non-virtual SkSVGNode to know about all possible state bits)

* add a "Type" suffix to SVG types, to disambiguate (e.g. SkSVGRectType vs.
  SkSVGRect)

Some spot testing makes it look like everything that's not a giant speedup can be made so by tweaking my (arbitrarily set) maximum size for the free list.

af06420cc1 Test sk_linear_to_srgb() less exhaustively in Debug mode. 
It's pretty slow when not optimized... it can take ~5 minutes to run.
This makes it take ~2 seconds on my laptop.

9c5052f16b SkLite* 
SkLiteRecorder, a new SkCanvas, fills out SkLiteDL, a new SkDrawable.

This SkDrawable is a display list similar to SkRecord and SkBigPicture / SkRecordedDrawable, but with a few new design points inspired by Android and slimming paint:

  1) SkLiteDL is structured as one big contiguous array rather than the two layer structure of SkRecord.  This trades away flexibility and large-op-count performance for better data locality for small to medium size pictures.

  2) We keep a global freelist of SkLiteDLs, both reusing the SkLiteDL struct itself and its contiguous byte array.  This keeps the expected number of mallocs per display list allocation <1 (really, ~0) for cyclical use cases.

These two together mean recording is faster.  Measuring against the code we use at head, SkLiteRecorder trends about ~3x faster across various size pictures, matching speed at 0 draws and beating the special-case 1-draw pictures we have today.  (I.e. we won't need those special case implementations anymore, because they're slower than this new generic code.)  This new strategy records 10 drawRects() in about the same time the old strategy took for 2.

This strategy stays the winner until at least 500 drawRect()s on my laptop, where I stopped checking.

A simpler alternative to freelisting is also possible (but not implemented here), where we allow the client to manually reset() an SkLiteDL for reuse when its refcnt is 1.  That's essentially what we're doing with the freelist, except tracking what's available for reuse globally instead of making the client do it.

This code is not fully capable yet, but most of the key design points are there.  The internal structure of SkLiteDL is the area I expect to be most volatile (anything involving Op), but its interface and the whole of SkLiteRecorder ought to be just about done.

You can run nanobench --match picture_overhead as a demo.  Everything it exercises is fully fleshed out, so what it tests is an apples-to-apples comparison as far as recording costs go.  I have not yet compared playback performance.

It should be simple to wrap this into an SkPicture subclass if we want.

I won't start proposing we replace anything old with anything new quite yet until I have more ducks in a row, but this does look pretty promising (similar to the SkRecord over old SkPicture change a couple years ago) and I'd like to land, experiment, iterate, especially with an eye toward Android.
