Bug: skia:10914
Bug: b/163595585
In a WebP image, it is possible to combine animation with an EXIF
orientation. While SkAndroidCodec attempts to handle orientation itself
by decoding into temporary memory and then drawing through a matrix,
this doesn't work directly when compositing a P-frame into a prior
frame. SkAnimatedImage already uses an SkMatrix to handle cropping and
scaling, so update that matrix to include the orientation.
Make SkAnimatedImage a friend of SkAndroidCodec. This allows the former
to have the same ExifOrientationBehavior specified by the latter, and to
recreate the latter so it does not try to handle the orientation itself.
Clip SkAnimatedImage to its bounds. Android's AnimatedImageDrawable
performs its own clip, but this makes a crop rect work for other
clients.
Update getCurrentFrame to take cropping, scaling, and orientation into
account. This method is used by CanvasKit, which does not use cropping
or scaling, but will now properly orient an animation with an EXIF
orientation.
Add a GM that exercises the various combinations of ways SkAnimatedImage
can be used:
- via newPictureSnapshot (as in Android) versus getCurrentFrame
- scaling down to a dimension that can be output from the
SkAndroidCodec, versus up, which SkAnimatedImage scales
- with a crop rect
- with a post processor

This also has several other bug fixes and refactorings within it that
I realized were possible while updating every where that had checked
sigma > 0 to be sigma > kEffectivelyZeroSigma.
The big things are that SkBlurPriv.h goes away and its functions are
just moved into SkGpuBlurUtils since they were only used by the GPU.
The implementations of those functions are also collected into
SkGpuBlurUtils.cpp. I removed the GrMatrixConvolution::MakeGaussian,
in favor of SkGpuBlurUtils filling in the kernel itself and then calling
the regular Make. This let me consolidate two different 1D kernel
computing functions, and remove the 1D fallback code from the 2D kernel
calculation because GaussianBlur() can detect that earlier.
The new GM, BlurSigmaSmall, originally drew incorrectly on the GPU
backend because it's small but non-zero sigma would trick the sigma > 0
checks in various places so we'd do a full 2 pass X/Y blur. However,
when the sigma was too small, the kernel was just filled with 0s so the
Y pass would effectively clear everything. While I could have just fixed
that to be a [0, 1, 0] kernel, updating the blur pipeline to compare
against integer radii seems more robust.

SkImageFilters::Paint did not use every slot of the SkPaint, with only
its color, alpha, color filter, and shader having a meaningful effect on
the image filter result. It was always blended into a transparent dst,
so blend mode wasn't very relevant, and it was always filled to whatever
required geometry, so stroke style, path effect, and mask filters were
ignored or not well specified.
Color, alpha, and color filter can all be combined into an SkShader, so
a more constrained SkImageFilters::Shader provides the same useful
capabilities without as many surprises.
SkImageFilters::Paint still exists, but is deprecated to be removed
once I've confirmed clients aren't depending on it.
