Each patch defines a method genMesh that produces the geometry to draw. To do this they receive a SkPatchMesh object which they need to initialize in order to set up how the data is going to be formatted. Later they call function like setColor or pointAt to set the values at a specific index, the SkMeshPatch object handles the indices based on the format and makes it transparent to the client.
Added a slide to sample app to show how to set up this classes and how they interact.

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.

Implement path tight bounds using path ops machinery. This is not
as efficient as it could be; for instance, internally, it creates
a path ops structure more suited to intersection. If this shows
up as a performance bottleneck, it could be improved.
Fix path ops gyp files, which have fallen out of sync with other
tests.

The interesting stuff is in SkPictureRecorder.{h,cpp}. The rest is mostly moving SkRecord from its own directories into core to avoid circular dependencies in GYP.
After plumbing SkRecord all the way through in Picture, I'll delete its old entry point include/record/SkRecording.h. For now it and record.gypi need to stay where they are to keep Chrome building.

Extract "text align proc" as reusable classes. These classes need to be used
when writing GrTextContext subclasses.
Moves "text align proc" code that is duplicated in SkDraw and
SkBitmapTextContext to SkDrawProcs.h and SkTextMapState.h. This functionality is
also used in the new GrStencilAndCoverTextContext.
Creates new functor classes SkTextAlignProc and SkTextAlignProcScalar which
represent the previous "text align procs".
Moves TextMapState from SkDraw to SkTextMapStateProc and make it similar functor.
The transform should be comparable in speed, as the compiler can and does avoid
the call and eliminate some of the branches.

This CL sets the stage for retracting the SkPicture::kOptimizeForClippedPlayback_RecordingFlag flag
from the public API (more work needs to be done in Blink & Chrome). In the new world the only way
to set this flag (and thus instantiate an SkPicture-derived
class) is by passing a factory to the SkPictureRecorder class. This is to get all clients always using
factories so that we can then change the factory call used (i.e., so the factory just creates a BBH) and
do away with the SkPicture-derived classes.

Add SkSmallAllocator, a template for allocating small (as defined by the
instantiation) objects without extra calls to new. Add a helper macro to
make using it simple.
Remove SkTemplatesPriv.h, whose behavior is replaced by SkSmallAllocator.
The old SK_PLACEMENT_NEW had the following drawbacks:
- Easily confused with SkNEW_PLACEMENT.
- Requires passing around lots of void*s along with the storageSize.
- Requires using a separate class for deleting it.
- We had multiple ways Auto objects for deleting in different places.
- It always did a straight heap allocation on Windows, meaning Windows
did not get any advantages from the confusing code.
The new SkSmallAllocator simplifies things:
- It is clear about what it does.
- It takes care of the deletion in one place that is automatically
handled.
Further, the new class can be used to create more than one object. This
is in preparation for BUG=skia:1976, for which we would like to create
a new object without extra heap allocations. The plan is to create both
the blitter and the new object on the stack using the SkSmallAllocator.
Add a new test for SkSmallAllocator.
SkShader.h:
Move the private version of CreateBitmapShader to SkBitmapProcShader
(which already has the implementation) and remove the friend class
(which was only used to call this private function). This allows
SkSmallAllocator to reside in the private src/ directory.
SkBitmapProcShader:
Move CreateBitmapShader and the macro for the storage size here. With
the macro in a (private) header, the (private) headers with function
declarations (which now depend on the storage size used) can see the
macro.
Use SkSmallAllocator in CreateBitmapShader.
Change the macro to kBlitterStorageByteCount, since SkSmallAllocator
takes a byte count as its template parameter.
SkBlitter:
Use the SkSmallAllocator.
Remove Sk3DShader::fKillProc and SkAutoCallProc. Both of their
behaviors have been moved into SkSmallAllocator (SkAutoCallProc was
unnecessary anyway, because the only time we ever used it we also
called detach(), so its auto behavior never happened).
Create the Sk3DShader on the stack, if there's room.
Remove the helper version of Choose, which was unused.
SmallAllocatorTest:
Test for the new class.
The rest:
Use SkSmallAllocator.

This patch includes a modified version of Chrome's trace_event.h, which provides
tracing macros that can easily integrate into the about://tracing framework.
Currently the macros link to a default implementation of the (narrow) tracing
class SkDefaultEventTracer which does nothing; next step will be to have Chrome
subclass the SkEventTracer with a shim that bolts Skia's trace events to its own,
allowing Skia's trace events to show up in about://tracing.
I've verified that this file builds properly, and when I added a simple scoped
TRACE_EVENT0 to SkCanvas::drawRect, along with some debug prints in the NOP
implementation of tracing, I saw what I expected printed to the screen.

Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.
What used to be this:
SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer
is now
SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer
Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed
This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.
