The order of arguments in these structs is arbitrary, so we might as well arrange them to optimize something. Putting the paints at the front means the logic to find the paint is a lot more concise: it's usually just ptr+0, or *(ptr+0) when the SkPaint is optional.
This considerably reduces the size of the jump table in IsDraw::operator().

The cubic line intersection math empirically works 99.99% of the time (fails 3100 out of 1B random tests) but when it fails, an intersection may be missed altogether.
The binary search is may not find a solution if the cubic line failed to find any solutions at all, but so far that case hasn't arisen.

When verylargebitmap GM runs in cross-process pipe mode, we're
requestBlock()ing ~200M to carry the bitmaps. The current
implementation ends up allocating ~800M, which is a bit wasteful.
SkGPipeWrite already rounds up to 16K, so just rely on that.
This change exposed several bugs in pipe:
- we don't reserve enough space in drawVertices
- we don't reserve enough space for factory names in cross-process mode
- we don't quite have the right check in needOpBytes to see if we needed to send off the current block and allocate a new one
SETUP_NOTIFY and generally calling doNotify() more often than necessary made things hard to debug and understand. Now the pipe always waits to send off its current block until it needs more space than that block can provide, or it's the final block. We can put these back if we need the proactive flushing, but it seems not necessary?
Removed an assert in DeferredCanvasTest, which is somtimes 2 (Debug), sometimes 3 (Release). It seemed like the other asserts were more essential, and this one was more of a white-box assertion. Still sound if we remove it?

If an saveLayer()/restore() is recorded, tilegrid/rtree will cull them
out and not draw anything. This is correct for most cases, but if the
paint in the saveLayer() is one that affects transparent black (e.g.,
it contains a color filter or image filter which affects transparent
black), this is incorrect: the filter should be applied.
Fixed by adding a no-op between the saveLayer() and restore(), and
adding a bbox node pointing at that node with the saveLayer()'s bounds.
This exposed a bug in SkPictureRecord.cpp's match(), where it would
assert if the NOOP was the last op seen. Fixed with an early-out before
calling peek_op_and_size().

This is a mid-level library for finding patterns of commands in an SkRecord. At the API level, it's a bit regex inspired. Some examples:
- Pattern1<Is<DrawRect>> matches a single DrawRect
- Pattern1<Star<Is<DrawRect>>> matches 0 or more DrawRects
- Pattern2<Is<ClipRect>, Is<DrawRect>> matches a single clip rect followed by a single draw rect
- Pattern3<Is<Save>, Star<IsDraw>, Is<Restore>> matches a single Save, followed by any number of Draws, followed by Restore
- Pattern1<Or<Is<DrawRect>, Is<ClipRect>>> matches a DrawRect or a ClipRect
- Pattern1<Not<Is<ClipRect>>> matches a command that's notClipRect.
Once you have a pattern, you can call .search() on it to step through ranges of matching commands. This means patterns can replace most of the custom iteration logic for optimization passes: the generic pattern searching steps through all the optimization candidates, which optimization-specific code further inspects and mutates.
SkRecordTraits is now unused. Bye bye!
Generated code and performance of SkRecordOpts is very similar to what it was before. (I had to use SK_ALWAYS_INLINE in a few places to make this so.)

Before this change, an object needed to inherit from GrResource (and
thus be a GPU object) in order to live in the GrResourceCache. That
was a problem for caching items that weren't GPU objects themselves,
but owned GPU objects.
This change splits GrResource into two classes:
1. GrCacheable: The base class for objects that can live in the
GrResourceCache.
2. GrGpuObject, which inherits from GrCacheable: The base class for
objects that get tracked by GrGpu.
This change is purely a refactor; there is no change in functionality.

When matrix convolution processes border pixels with zero width, it
asserts in getAddr32() with an invalid x coordinate. The assert is
harmless, since the returned pointer is never accessed (the next line
is a loop from left to right, which does nothing, since left == right).
However, the fix is simple: early out on an empty rect before entering
the outer loop.

The old code here wasn't being careful to avoid int32_t overflow in slow_check. Fix that.
R_ASSERT hasn't been doing anything for a while. As a result, there are a couple bugs in SkClampRange, marked as such and commented out. The asserts also weren't quite passing, so I fixed them up (allowing 0xFFFF to be considered either as part of the ramp or part of V1.)

On Mike's suggestion, I tested out not doing any empty-clip check at all in
SkRecordDraw, given that mostly we'll do that again anyway inside SkCanvas.
Most SKPs are identical to the status quo, whether bot or silk, played back in tiles
or full. Average playback performance, both arithmetic and geometric mean, is also
unchanged.
A handful of SKPs do draw faster or slower reliably, particularly when tiled. E.g. a
cnn tile draws about 40% faster, a cuteoverload tile about 20% slower. Their profiles
look pretty much the same before and after, so I can't really explain the changes.
I'd say, given that performance is mostly identical and very identical in bulk,
we might as well remove this code. It's nice to keep SkRecordDraw as dumb as possible.

Add a new GM that exercises tiled drawing all pixel-moving filters
(and some non-pixel-moving ones) and compares it against non-tiled
drawing of the same filters. Fixing this test revealed that tile and
matrix convolution filters had no onFilterBounds() traversals
(test-driven development FTW). Tile requires (conservatively) the
bounds to include the whole source rect, since it may end up in the
result. Matrix convolution requires the bounds to be offset by the
kernel size and target.
