When adjusting the CTM for filter use, we were subtracting off the
destination coordinates of the drawDevice() or drawSprite(). This is
not quite correct: we should subtract off the coordinates relative to
the device origin instead. This occurs when one filtered saveLayer() is
drawn inside another saveLayer(), both with non-zero origin.
This fixes layout test svg/batik/text/smallFonts.svg in Blink, and is
exercised by the provided unit test.

If one of inputs to SkXfermodeImageFilter draws nothing, either due to
it being cropped out upstream, or within the filter itself, the filter
should still draw the other input, since otherwise the result will be incorrect.
For the GPU path, since we can't detect this case in
canFilterImageGPU() without recursing, we'll just drop to
the generic path if either input is empty, since we can't use the effect in that case anyway.
While we're at it, let's drop to the generic path if the
xfermode can't be expressed as an effect, since the code
here was doing a 2-pass render in that case anyway, which
is equivalent to what the (xfermode == NULL) case was doing
anyway.

This was crashing on the GPU path, due to a failed texture allocation.
The belt-and-suspenders fix is to:
1) Limit the GPU path to only allocate up to maxTextureSize.
2) Limit both the raster and GPU paths to reasonable blur sizes (box blur
kernel size of 1000, resulting in a sigma limit of 532).

NOTE: this patch set is based on https://codereview.chromium.org/189913021/,
and needs that patch to land first.
Until now, crop rects in Skia have only been able to reduce
the size of the destination bounds, but not expand them.
SVG semantics require the latter as well. The heart of
the change is in applyCropRect(), which now assigns each
edge, instead of doing an intersection with the crop rect.
In order to support this (and still work well with tiled
drawing) we need to clip the resulting crop rect to the
clipping region of the filters. This uses the Context struct
previously landed from https://codereview.chromium.org/189913021/.
Many of the pixel loops are not yet ready to handle a
destination rect larger than the source rect. So we provide
a convenience version of applyCropRect() which creates an
offscreen and pads it out with transparent black. Once the
pixel loops and shaders have been fixed to support larger
destination bounds, they should be switched back to the
non-drawing version of applyCropRect().

Some upcoming work (support for expanding crop rects) requires
the clip bounds to be available during filter traversal. This change
replaces the SkMatrix parameter in the onFilterImage() traversals
with a Context parameter. It contains the CTM, as well as the clip
bounds.

This is part of an effort to ensure that all SkPaint effects can only be
allocated on the heap.
This patch makes the constructors of SkImageFilter and its subclasses non-public
and instead provides factory methods for creating these objects on the heap. We
temporarily keep constructor of publicly visible classes public behind a flag.

The matrix used during filter application should be up-to-date, so that
the filter parameters can be scaled by the CTM (e.g., for hiDPI).
However, tiled playback defers setting of the matrix until after the
restore() call which draws the filter, which is too late. Moving the
setMatrix() ahead of the restore() sequence fixes the problem.

Also factored the crop offset unit test into a function, so we can

relative to their parent's crop rect. This is required by SVG semantics, and is more sane anyway.
To do this, this patch changes the "offset/loc" parameter in filterImage() / onFilterImage() from an inout-param to an out-param only, so that the calling filter can know how much the input filter wants its result offset (and doesn't include the original primitive position). This offset can then be applied to the current filter's crop rect. (I've renamed the parameter "offset" in all cases to make this clear.) This makes the call sites in SkCanvas/SkGpuDevice responsible for applying the resulting offset to the primitive's position, which is actually a fairly small change.
This change also fixes SkTileImageFilter and SkOffsetImageFilter to correctly handle an input offset, which they weren't before. This required modifying the GM's, since they assumed the broken behaviour.
NOTE: this will require rebaselining the imagefiltersgraph test, since it has a new test case.
NOTE: this will "break" the Blink layout tests css3/filters/effect-reference-subregion-chained-hw.html and css3/filters/effect-reference-subregion-hw.html, but it actually makes them give correct results. It should be suppressed on the skia roll, and I'll rebaseline it.

Last week, the fuzzer found a few numerical issue with filters and I had written some fixes for them. Here are the fixes with some unit tests.
For senorblanco : So I figured out what was asserting when we'd get a 0 width "result" in SkBicubicImageFilter::onFilterImage(). Basically, if the "result" SkBitmap object calls SkBitmap::setConfig() with "width" and/or "height" set to 0, then the SkBitmap object will call SkBitmap::reset(), making the SkBitmap object's config invalid. At this point, calling SkBitmap::getAddr32() will assert, even without attempting to dereference the data pointer, because the SkBitmap's config is invalid. If height is valid, but width is 0, then this call to SkBitmap::getAddr32() happens directly in SkBicubicImageFilter::onFilterImage() a few lines lower and asserts right away.

for SkColorFilterImageFilter and SkBlurImageFilter as examples.
In order to preserve the immutability of SkImageFilters, the crop rect is passed as a constructor parameter. If NULL (the default), the bounds of the input image are used, as before.
This also tightens up the boundary handling for SkImageBlurFilter on the GPU backend. Where we were previously using clamping semantics, we now respect decal semantics (so we don't oversaturate the edges). This brings the GPU and raster backends into closer alignment, but will require some new baselines for the GPU tests.
At a minimum, the following tests will need new baselines: imageblur, imagefiltersbase, imagefilterscropped, spritebitmap.
