c4b12f19a4 Implement correct clipping for image filters.
Image filters in Skia currently clip the size of the the offscreen
bitmap used for filtering to the device clip bounds. This means that
any pixel-moving filter (e.g., blur) has edge artifacts at the clip
boundaries. This is problematic for tiling, where a single SkPicture
is played back with a clip set to the tile boundaries.

By implementing the onFilterBounds() traversal, and using it in
saveLayer() when a filter is present, we can clip the layer to the
expanded clip rect. Note that this requires that the traversal be
performed in reverse as compared to computeFastBounds().  (It's also
done in device space, unlike computeFastBounds()).

New test imagefiltersclipped tests pixel-moving filters when clipped
by various clip rects.
New test imageblurtiled tests tiled (compositor-style) rendering of
blurred text. There should be no artifacts at the tile boundaries.

ea6e14a382 TSAN: use somewhat pithier SK_ANNOTATE_UNPROTECTED_READ.
This is a little bit better practice to be i than the existing SK_ANNOTATE_BENIGN_RACE, as UNPROTECTED_READ will only ignore reads, not writes.

Tag SkRefCnt::unique() as a safe unprotected read like SkOnce's double-checked locking.

6169f2b4da initial import of Chrome's trace_event into skia framework
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.

a2bd2d12ad Set write buffer flags only in SkWriteBuffer and SkFlatController constructors.
This is a baby step toward refactored (and faster in-process) typeface and flattenable factory encoding and decoding.  The sooner SkWriteBuffer knows its flags, the better.

Next steps will be to rearrange Sk{Read,Write}Buffer members into disjoint strategies to handle typefaces and flattenable factories: one for in-process, one for cross-process, one when validating.

8b0e8ac5f5 Refactor read and write buffers.
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.
