a6841be235 Enable ClangTidy check llvm-namespace-comment.
This fixes a large number of SkSL namespaces which were labeled as if
they were anonymous, and also a handful of other mislabeled namespaces.
Missing namespace-end comments have been added throughout.
A number of diffs are just indentation-related (adjusting 1- or 3-
space indents to 2-space).

bf8439d7e2 Fix GMs broken during API porting
Bugs:
morphology GM: Had swapped Erode and Dilate
imagefilterscropexpand GM: Was applying the filter to the wrong rectangle
imagefilterstransformed, filterfastbounds, et al GMs: The new
SkImageFilters::Image() factory had defaulted to using kNone for quality,
since it appeared to keep a 1-to-1 scale. However, it actually draws the
image from srcRect into the dstRect, mapped by the CTM, so if there's a
scaling factor in the CTM the filter no longer is 1-to-1 and kNone leads
to weird scaling artifacts. So switched back to the original kHigh default.

7fde8e1728 IWYU for gms.
This almost gets gms to be iwyu clean. The last bit is around gm.cpp
and the tracing framework and its use of atomic. Will also need a way
of keeping things from regressing, which is difficult due to needing to
do this outside-in.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

No-Presubmit: true

Adapting gray to 565 will add a noticeable purple/green tint.
I'd rather only the 565 images in Gold were tainted with that.

33d2055e59 GM: some header cleanup
gm.h includes sk_tool_utils.h but does not use it.

The bulk of this CL makes each gm that uses sk_tool_utils include it.

sk_tool_utils.h also provided SkRandom and SkTDArray,
so a couple GMs add those headers too.

3949971e8d Image filters: fix filtering of transparent black in CFIF.
SkColorFilterImageFilter has a codepath to filter transparent black
regions outside of the input image. However, it was treating the
exterior as opaque black, rather than trasparent black.

Note: the results of imagefiltercropexpand GM will change, as it
was tweaked a bit to show this bug.

c834ab178e Fix gaussian blur for small sigma.
I broke this in https://skia.googlesource.com/skia/+/c57e0ded7d535523cfc6bf07c78e5f3479bb8c42.
That change added support for cropping during blur, but
did not do the correct thing for the small-sigma 2D matrix convolution
optimization when blurring from small-to-large textures.

The fix is pass the correct dstRect and srcOffset to convolve_gaussian_2d.
I also changed convolve_gaussian_1d() and convolve_gaussian_2d() to take
the original (non-negated) srcOffset, and to negate them when constructing
the local matrix.

Test: added a new (blur 0.3 0.3) column to imagefilterscropexpand, so that
GM will have to be rebaselined.

24e06d5244 Remove uniqueID from all filter serialization.
(This is essentially a revert of https://codereview.chromium.org/503833002/.)

This was necessary back when SkPaint was flattened even for in-process use. Now that we only flatten SkPaint for cross-process use, there's no need to serialize UniqueIDs.

Note: SkDropShadowImageFilter is being constructed with a croprect and UniqueID (of 0) in Blink. I've made the uniqueID param default to 0 temporarily, until this rolls in and Blink can be changed. (Blink can't be changed first, since unlike the other filters, there's no constructor that takes a cropRect but not a uniqueID.)

234f036b3e Adding an option to render only the shadow in SkDropShadowImageFilter
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.

118252962f Implement support for expanding crop rects in image filters
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().
