Reason for revert:
Introduced memory leak; pixel changes in Chrome.

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.

When the parallel stroke to the curve can't be computed from
the intersection of the tangent lines, as straight line connects
the two points instead. Allow the intersection to succeed unless
the ratio isn't finite or the contribution of (1 - ratio) isn't
significant.

If the client wants no caching, and we haven't already cached it, pass the
caller's dst-buffer directly down to the generator, avoiding the (previous)
extra memcpy.

This shouldn't really make any difference but allocating and holding on to a GrRenderTarget for each test target generates image differences for Mali GPUs. This CL allows an existing render target to be used for the test target.

Makes it so that the oversized-texture/bmp case doesn't run on the CPU and makes it so that the subrect rendered is adjacent to the texture pad area on the bottom/right edges.

This allows internal Gr texture creation code to succeed for extraneous textures while running the bleed GM. This means we can turn on the shader variants.

An additional positive of this CL is that GrGLShaderBuilder is now GL independent besides GrGLProgramBuilder

Reason for revert:
re-land once layout test have been disabled (so they can be rebased)

This change updates feSpotLight to match the spec via two changes:
1) specularExponent is ignored if the spotlight has no coneAngle (GPU
bug only). This change updates the GPU path so that it matches the
CPU path and the spec in this regard.
2) specularExponent is clamped to the 1-128 range. The spec does not
specify a clamp for the specularExponent attribute of feSpotLight.
Note that the spec *does* specify this clamp for the
specularExponent attribute of feSpecularLighting. It looks like we
incorrectly applied this to both specularExponent attributes.
This change (along with a parallel change in Blink) allows us to pass
the SVG filter effects conformance test here:
http://www.w3.org/Graphics/SVG/Test/20110816/harness/htmlObject/filters-light-01-f.html
Additionally, this brings our behavior in line with Safari and Edge’s
behavior on this filter.
Two new cases were added to gm/lighting.cpp to catch these issues:
- The existing spotlight case exercised the path where our specular
exponent was between 1-128 and had a limiting cone angle.
- The first new spotlight case exercises the path where our specular
exponent is between 1-128 and we do not have a limiting cone angle.
- The second new spotlight case exercises the path where the specular
exponent is not within the 1-128 range, to ensure that we don’t
incorrectly clip to this range.

premultiplied colors, however the flag for whether or not to do this,
which is present in their parent filters, is dropped when creating the
GL implementations. This change adds logic to forward the value from
the parent filter to the GL implementation.
This makes GPU behavior match software and fixes a WebKit
LayoutTest. See referenced bug.

The result is that the set of "generic" imagefilters (e.g. SkColorFilterImageFilter) that use drawing commands to return their results will now stay in the same domain as their src (i.e. gpu-src --> gpu-dst).
ApplyFilterGM exercises this, and now asserts this same-domain invariant.

This method is different from MatrixFilter, in that MatrixFilter does not require a pre-existing
filter, but LocalM does. Also change the comment to be more general, as there is no promise that
we return a different subclass, and certainly not a specific subclass.
This pattern of obj->newWithModifiers() also more closely matches the pattern in SkImage (newSubset).

At draw time, this filter simply concatenates the given matrix to the
CTM, and recurses on its input. The matrix is thus applied to any
upstream filter parameters and crop rects.
