8640d5024d This patch adds support for optional processing of the alpha channel in
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.

5faa2dc266 Implements a matrix convolution filter (raster path only). The filtering loop
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".
