The SkRectShaderImageFilter had the same bug as previously fixed for
SkBitmapSource and SkPictureImageFilter. Rather than copy-and-paste
the implementation, this change makes all filters with 0 inputs return
their source bounds, instead of returning false.

This is basically how blink uses the filter. Currently, I can't use it for "ShadowOnly" mode with the filter at all, but instead of copying the code and risking to have the codepaths diverge, I'm simply going to add the option here.

9fa60d ("Simplify flattening to just write enough ... ") simplified just
a tad too much. In particular, it disabled deserialization of
SkImageFilter's uniqueID, which in turn caused the failure of
SkImageFilter's cache, which caused a large regression in Chrome's SVG
filter performance.
The medium-term fix is to switch to the new SkRecordDraw SkPicture
backend, which will make the unique IDs unnecessary.
This change is an "in case of emergecy" CL, in the event that there are
problems switching on the new backend in Chrome. For that reason, it's
minimalist: only the filters used by Chrome are modified, and whitespace
changes are kept to a minimum. In this way, it should be easy to revert
once the new backend goes in.

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.

When drawing perlin noise, generate noise at the resolution determined
by CTM, not by the resolution at construction time. This required moving
the generation of PaintingData to getContext() and asNewEffect() for the
raster and GPU paths, respectively.
It also required adjusting the matrices used during rendering
to be translate-only.

From inside GrContext, we have a need to create an SkPath an original path and
some dashing info. We do not have access to the original path effect so we need
a way to make the FilterPath function accessible outside of the effect. So I moved
the core filterPath code (and all need helper functions) out of SkDashPathEffect
and created a SkDashPath in utils to store these helper functions.

The new signature is:
bool asNewEffect(GrContext* context, const SkPaint& paint, GrColor* grColor, GrEffectRef** grEffect, const SkMatrix* localMatrixOrNull) const;
It will fix the hack for skcolorshader by modifying the GrColor parameter in SkGr::SkPaint2GrPaintShader.

In SkLayerRasterizer::snapshotRasterizer() and ::detachRasterizer(),
if no layers have been added, do not attempt to create an
SkLayerRasterizer. Instead, return NULL.
This fixes an error when running tests on Android.
Update dox to state that NULL may be returned.
Add tests.

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.
