[fxtf-drafts] [filter-effects-1] hue-rotate color space could be explained better (#473)

pshaughn has just created a new issue for https://github.com/w3c/fxtf-drafts:

== [filter-effects-1] hue-rotate color space could be explained better ==
https://drafts.fxtf.org/filter-effects/#funcdef-filter-hue-rotate says just "Applies a hue rotation on the input image", which I think most first-time readers would generally expect to be a rotation in something like RGB or HSV or HSL space. The matrix is specified in  https://drafts.fxtf.org/filter-effects/#ref-for-attr-valuedef-type-huerotate without any explanation of how the coeffecients were decided. This seems to be a rotation in YIQ colorspace or something similar, and the spec could be more explicit about that.
