traversal which respects the CropRect. This is useful when
you want the device-space bounds of a primitive after
filtering. (This may also eventually subsume
computeFastBounds()).
This CL generalizes filterBounds() and onFilterBounds() to
take a mapping direction. It also makes filterBounds()
responsible for calling onFilterNodeBounds() and applying
the crop rect, simplifying onFilterBounds().

In the current implementation, a blur filter is always created even in the
case when sigma.fX == 0 && sigma.fY == 0. This CL makes the blur filter
return input in this case.

Make each filter responsible for expanding its destination
bounds. Previously, we were using a union of all
intermediate bounds sizes via join() calls in many image
filters' computeFastBounds(), due to the fact that those
filters could only produce bitmaps the same size as their
inputs. Now, we compute optimal bounds for each filter as
follows:
1) Pass the (unmodified) clip bounds to the root node
of the DAG in the first recursive call to onFilterImage()
as the Context's fClipBounds.
2) Reverse-map the clip: when recursing up the DAG in
filterInput[GPU](), apply filter-specific expansion to the
clip by calling calling onFilterNodeBounds(... kReverse).
This allows upstream nodes to have a clip that respects the
current node's requirements. This is done via helper
function mapContext().
3) Forward-map the source bitmap: just prior to applying
the crop rect in applyCropRect(), we determine the filter's
preferred bounds by mapping the source bitmap bounds
forwards via onFilterNodeBounds(..., kForward).
NOTE: GMs affected by this change:
fast_slow_blurimagefilter: fast and slow paths now produce the same result
spritebitmap: drawSprite() and drawBitmap() paths now produce the same result
filterfastbounds: fast bounds are optimized; all drop-shadow results now appear
apply-filter: snug and not-snug cases give same results
dropshadowimagefilter: drawSprite() results now show shadows
draw-with-filter: no artifacts on erode edges; blur edges no longer clipped
displacement, imagefiltersbase, imagefiltersclipped, imagefilterscropexpand, imagefiltersscaled, matriximagefilter,
resizeimagefilter, localmatriximagefilter, testimagefilters: fixed incorrect clipping
imagefilterstransformed, morphology: no artifacts on erode edges

Because the convolution kernel is (currently) applied in device space,
there's no way to know which object-space pixels will be touched. So
return false from canComputeFastBounds().
The results from the matrixconvolution GM were actually wrong, since
they were showing edge differences on the clip boundaries, where they
should really only show on crop boundaries. I added a crop to the GM
to keep the results the same (which are useful to test the different
convolution tile modes).
While I was at it, SkImageFilter::affectsTransparentBlack() was
inapplicable on most things except color filters, and its use on
leaf nodes was confusing. So I removed it, and made
SkImageFilter::canComputeFastBounds() virtual instead.

To avoid breaking existing SKPs, add a deserialization stub which

The Registrar class is unnecessary, as SkFlattenable factory
registration is now handled via initialization routines that can just
call the Register function directly.
Also, no need to lazily initialize gCount to 0, as initializing an int
to a constant value does not require dynamic initialization. (C++
actually guarantees zero initialization of global ints anyway, but
existing practice in Skia appears to favor the explicit "= 0").
Relatedly, this requires removing the unused/unimplemented
SkLayerDrawLooper::MyRegistrar class. And removing that allows Clang
to realize that SkLayerDrawLooper::fTopRec is unneeded too, so remove
that too to squelch the compiler warning/error.
This doesn't change any public API.

Blink is migrating away from SkBitmaps, so we need an SkImage-based
SkImageFilter source. This is pretty much a 1-1 equivalent of
SkBitmapSource.
To avoid duplication, relocate the SkImage deserialization logic
from SkPictureData to SkReadBuffer.

Image filters have never implemented this check, which means that
filters which affect transparent black falsely claim they can compute
their bounds.
Implemented an affectsTransparentBlack() virtual for image
filters, and a similar helper function for color filters.
This will affect the following GMs: imagefiltersscaled
(lighting, perlin noise now filter to clip),
colorfilterimagefilter (new test case), imagefiltersclipped
(perlin noise now filters to clip).
Note: I de-inlined SkPaint::canComputeFastBounds() to avoid adding
a dependency from SkPaint.h to SkImageFilter.h.h. Skia benches show
no impact from this change, but will watch the perf bots carefully.
