Multiple Master and TrueType fonts support variation axes.
This implements back-end support for axes on platforms which
support it.

d8b5771779 Don't fail SkMergeImageFilter if one of the inputs are empty
If one of the inputs to a SkMergeImageFilter was clipped away or
otherwise caused the filterImage(...) invocation for it to return
false, the entire effect would be "failed" and return false --
regardless of if it had produced a result or not.
Instead of returning false directly if filterImage(...) for a source
returned false, consider all the inputs, and then only return false if
all of them do.

9db912c2ac Sketch splitting SkPicture into an interface and SkBigPicture.
Adds small pictures for drawRect(), drawTextBlob(), and drawPath().
These cover about 89% of draw calls from Blink SKPs,
and about 25% of draw calls from our GMs.

SkPicture handles:
  - serialization and deserialization
  - unique IDs

Everything else is left to the subclasses:
  - playback(), cullRect()
  - hasBitmap(), hasText(), suitableForGPU(), etc.
  - LayerInfo / AccelData if applicable.

The time to record a 1-op picture improves a good chunk
(2 mallocs to 1), and the time to record a 0-op picture
greatly improves (2 mallocs to none):

    picture_overhead_draw:   450ns -> 350ns
    picture_overhead_nodraw: 300ns -> 90ns

5b5ddd73b4 The path ops builder code needs to determine the winding of each contour added, and reverse windings if the contours are nested in other contours.
Cheap (one contour) paths can be evaluated and reversed as needed with a minimum of checking, but multi-contour paths invoke the regular path ops machinery to determine who is contained by whom.

More tests need to be added to verify that all corner cases are considered, but this fixes the cases in the bug thus far.

fba9da78ac fix path op builder
The rewrite of path ops caused the inner contour direction to be reversed.
This exposed an existing bug in path ops builder, namely that the implicit
winding of the internal sum path could hide inner contours if they ended
up in the wrong direction.

Setting the sum path's fill type to even-odd ensures that the inner
contours aren't discarded.

624637cc8e Path ops formerly found the topmost unprocessed edge and determined its angle sort order to initialize the winding. This never worked correctly with cubics and was flaky with paths consisting mostly of vertical edges.
This replacement shoots axis-aligned rays through all intersecting edges to find the outermost one either horizontally or vertically. The resulting code is smaller and twice as fast.

To support this, most of the horizontal / vertical intersection code was rewritten and standardized, and old code supporting the top-directed winding was deleted.

Contours were pointed to by an SkTDArray. Instead, put them in a linked list, and designate the list head with its own class to ensure that methods that take lists of contours start at the top. This change removed a large percentage of memory allocations used by path ops.

0d992db1cf Make SkFunction copyable so it can go in containers.
This totally overhauls the implementation to use ordinary inheritance-based type erasure.  I give up for now getting my manual vtable shenanigans to work with MSVC.  Still those same "expected ; before ), also expected ) before ;" errors.

I added support for uninitialized SkFunctions and operator=(), because it was fairly straightforward with this implementation.

The main downside here is that I've removed the inline implementation.  All SkFunctions involve a heap allocation, even when just wrapping function pointers.

aec2510125 minor fixes to cubics code and overall alignment of how bounds and tops are computed for all curve types
All but 17 extended tests work.

A helper function is privately added to SkPath.h to permit a test to modify a given point in a path.

5b6db07fb5 SkRWBuffer for thread-safe 'stream' sharing
WIP
- Can accumulate (write) data in one thread, and share snapshots of it in other threads
  ... e.g. network accumulates image data, and periodically we want to decode/draw it
- If this sort of thing sticks, should we promote SkData to have the same generality as
  SkRBuffer?

cfc18867d9 Use GLSLCaps for creating processor keys and GLSL-specific programs
Effectively all this does is future-proof any GLSL-specific code, as
GLSLCaps is just a typedef of GLCaps.

d7c014ff03 Split rsqrt into rsqrt{0,1,2}, with increasing cost and precision on ARM
This is a logical no-op.  Everything was using the equivalent of rsqrt1() before, and is now after.

1113da72ec Mike's radial gradient CL with better float -> int.
patch from issue 1072303005 at patchset 40001 (http://crrev.com/1072303005#ps40001)

This looks quite launchable.  radial_gradient3, min of 100 samples:
  N5:  985µs -> 946µs
  MBP: 395µs -> 279µs

On my MBP, most of the meat looks like it's now in reading the cache and writing to dst one color at a time.  Is that something we could do in float math rather than with a lookup table?
