The CPU blitters use signed 32-bit offsets when gathering source pixels,
so any image larger than that can't be fully indexed. Instead, we'd wrap
around and sample from invalid memory. This does put a new (smaller)
limit on valid image sizes, but it seems unlikely to impact any client.

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.

Note: The polarity of the staging flag is inverted from usual because
a G3 dependency with no SkUserConfig.h relies on the legacy API.
Once this lands, we will migrate them and others, then remove the
staging API. The inverted staging flag is kind of nice, actually - I may
use that pattern in the future. It means less total CLs and it's just as
easy to flip the bit on or off during debugging.

When mapping the radii, use the magnitude of a vector built from each
component of the radii instead of considering the radii as a plain

This folds the source SkSpecialImage, that was previously passed in as
an argument to filterImage(), into the filtering Context. This allows
the Context to provide convenient access to backend properties that
are only accessible through the source image, but makes it clear in
calling code that the actual pixels of the source image are not needed.
IMO this improves readability in implementations that previously had
functions that would take a 'src' and an 'input' image, but would only
really process the input image's pixels.

This moves OutputProperties' fields into Context and decouples SkSpecialImage
makeSurface() functions from SkImageFilter_Base.
It adds a utility makeSurface() function to Context that calls the SkSpecialImage
functions. Currently that requires the source image to be provided to it.
In a later CL, Context will hold the source image and this makeSurface() function
will be even simpler to use.
