733f5f5dbc Refactor SkGrFontScaler and SkGrFontKey into non-virtual versions.
This is a pre-cleanup for another change, but has the side benefit of making
the code simpler in general.

No perf increase, despite removing virtual functions.

936b73424f ios fixes
skia_ios.mm
Get the app's Documents directory and pass use it to set the resource path.
This is a quick hack which will be replaced by a new application that is
a tiny shim around a command line tool.

SkImageEncoder.h
SkForceLinking.cpp
SkImageDecoder_CG.cpp
Add support for FORCE_LINKING so iOS sees the PNG encoder and others.

SkFloatBits.cpp
SkPoint.cpp
Handle denormalized numbers that are floored by the iOS ARM processor.

SkImageDecoder_iOS.mm
Remove empty encoder factory.

SkTouchGesture.cpp
Return early on empty state on touch rather than aborting (crashing)

JpegTest.cpp
Hal via stackoverflow.com says partial jpegs can be gray as well.

skia_test.cpp
Remove crash handler call for now to avoid link failure.

OverwriteLine.h
Remove fancy line overwrite for iOS.

Resources.cpp
Add interface to set resource directory based on runtime query.

848faf00ec This moves us towards variable length effect keys. The overall program key now allows for it. After the header it stores an array of offsets to effect keys. This allows us to grab the effect keys to pass to effects when they generate code. It also ensures that we can't get a collision by sets of keys that are different lengths but are the same when appended together.

42483d9026 Split SkTRacy into SkTRacy and SkTRacyReffable.
Looks like TSAN can't always suppress our existing implementation of SkTRacy

SkTRacy where possible and SkTRacyReffable where necessary.

db5f7bf0a4 Do not export SkTDArray when building Skia as a DLL
This class has four members (deleteAll, freeAll, unrefAll and
safeUnrefAll) which will only compile for certain instantiations of
SkTDArray depending on the template argument type.  Marking this class
as dllexport breaks the build with clang-cl because of
http://llvm.org/PR20163.  Since this class is header-only, we can just
make it non-exported to enable building Skia as a DLL with clang-cl.

0b544ae222 Add SkRacy
SkRacy<T> is a zero-overhead wrapper for a T, except it also
silences race warnings when TSAN is running.

Here we apply in several classes.  In SkMatrix and SkPathRef,
we use it to opportunistically cache some idempotent work.

In SkPixelRef, we wrap the genIDs.  We think the worst that
can happen here is we'll increment the global next-genID a
few times instead of once when we go to get another ID.

9ea3d57fde Clean up SkImageFilter constructors.
Now that all creation of SkImageFilters goes through
factory Create() methods, there's no real reason for the
convenience constructors. Some SkImageFilter subclasses
which actually have zero DAG-able inputs were passing NULL
to the superclass constructor. This actually means 1 input,
with a NULL value, not zero inputs. This becomes more
relevant for the upcoming cache infrastructure, where this
indicates that the filter will use its src input, where in
fact some of these filters do not (they are image generators
only).

Limiting SkImageFilter to a single constructor resolves this
ambiguity.

Along the way, I removed all of the default parameters to
the constructors, since the Create methods always call them
with the full argument list.

2011fe9cdf Make GrDrawState and GrPaint take GrEffect* instead of GrEffectRef*.
Make Sk-effect virtuals produce GrEffect* rather than GrEffectRef*

Make GrEffectRef a typedef for GrEffect.

9a9eae21ed change pixelref to not inherit from SkFlattenable
If I can "inline" MallocPixelRef unflatten, then I think we can delete this code. The only caller today should be unflattening in the legacy path for bitmaps.

ce4dd3de38 Split SkPicturePlayback out of SkPictureData
This splits the playback functionality out of SkPictureData. The old SkPictureData::draw method is pulled out along
with its supporting functions as verbatim as possible. Some follow on CLs will be required to:

   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)
   Clean up CachedOperationList (maybe fuse with SkPicture::OperationList)
   Split SkPicturePlayback into a base class and two derived classes
   Implement parallel version of GatherGPUInfo for SkRecord

Landing this is blocked on removing Android's use of the abortPlayback entry point.
