[SVG1.1] feDiffuseLighting calculation does not define I(x,y)

The normal calculation in section 15.14 defines N in terms of a
function "I(x,y)", which does not appear to be defined.  I would guess
this is intended to be some variety of intensity/luminance function,
but it should be explicitly stated.
