Re: [csswg-drafts] [filter-effects] feComposite (Porter-Duff) operator values do not match those defined in the referenced [compositing-1] spec (#5267)

The values in compositing-1 only apply to Canvas and not to SVG as written in the spec. The Filter Effects spec extended SVG 1.1 filters to include "non-duplicated" composing values in Compositing 1. See:  [Changes section of Filter Effects]( The prose in [the feComposite section]( does not mention this change... so either it was removed and not noted in the changes section or it never was properly added. (The additional operators should not require swapping 'in' and 'in2'.)
