the matrix convolution filter. Test cases are added to the GM and the
bench.
NOTE: This will require rebaselining the matrixconvolution GM, so it will
likely turn the bots red until that is done.

is templated on the tiling mode for speed: interior pixels are unconditionally
fetched; border pixels apply the appropriate tiling mode before fetching. It
handles target, bias, divisor (as gain), and edge modes (named to be more
skia-like). It does not handle the "preserveAlpha" semantics of
feConvolveMatrix, nor "kernelUnitLength".
