Tyler Denniston 7bb85dbb5e [svg] Add plumbing for color-interpolation-filters property
The default colorspace for filter effects is linear RGB, as specified in
https://www.w3.org/TR/SVG11/painting.html#ColorInterpolationProperties.
Currently we perform all filtering in the destination colorspace. This
CL adds the new presentation attribute with the default setting
(according to the spec) of linear RGB.

This CL does not actually implement any colorspace transformations for
filters.
