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.

Result:
- clients can get a filtered version of an image without having to setup a temp drawing environment
- for some cases, the process is more efficient even than (deprecated) drawSprite, since there is no need to draw/copy the result
Impl:
- made Proxy virtual so we don't need to have an existing device to use it
This, in conjunction with LocalMatrixImageFilter, should allow us to simplify and optimize ApplyImageFilter() in cc/output/gl_renderer.cc

The "zeroPath" and emptystroke GMs capture this issue.
This CL changes the following PDF GMs: emptystroke dashing4
lineclosepath dashing3 zeroPath linepath
complexclip3_complex complexclip3_simple roundrects
degeneratesegments filltypes strokerect pathfill
inverse_paths desk_chalkboard.skp
After this change, all PDF GMs look better (closer to 8888).
The dashing4, emptystroke, and zeroPath GMs still need a lot
of work to make them look right.

drawImage calls now properly embeds the original jpeg.
NOTE: drawBitmap*() calls no longer embed JPEG files when
possible (this is in advance of eliminating bitmaps backed
by encoded data). Chromium has already moved from
drawBitmap to drawImage.
Comparisons:
control:
total PDF drawImage/drawBitmap calls: 8010
total PDF jpeg images: 0
total PDF regular images: 3581
experiament:
total PDF drawImage/drawBitmap calls: 8014
total PDF jpeg images: 271
total PDF regular images: 3311
total PDF regular images: 3582 (271 + 3311)
When comparing rendered output there were perceptual
differences in the following four GMs: colorcube, emboss,
colormatrix, and tablecolorfilter. All of these differences
were improvements (that is, closer to the 8888 rendering)
due fixing a bug with colorfilters and forgetting to call
notifyPixelsChanged.
No SKPs had perceptual differences.
Total PDF size dropped from 133964 kB to 126276 kB, a 5.7%
improvement (mostly due to restoring use of JPG images in
SKPs).

An alternative way of addressing this is to alter SkCanvas::drawRoundRect to just reject isEmpty (i.e., un-sorted or truly empty) input rects.

One side effect is that the SkShader's (or implicit shader's) fragment processor is responsible for the transition from an unpremul paint color to a premul color.

To avoid breaking existing SKPs, add a deserialization stub which
unflattens SkBitmapSource records to SkImageSources.

Previously annotations added between saveLayer/restore were lost.
Merge annotations in SkPDFDevice::drawDevice(). Also modified code to
apply correct transformation and clipping on annotations added between
saveLayer/restore:
- Apply the initial transform only when adding the annotations into the
doc, otherwise we need to unapply sub-device's initial transform
before merging the annotations into parent-device.
- Apply only device-local clipping. fClipStack is in global coordinates,
which is not suitable to clip rects in sub-devices.
