Details
Both offset-path:path() and clip-path:path() use a svg path to build the a gfx::Path. The unit of the gfx::Path built for offset-path is CSS pixel [1], but the unit of the gfx::Path built for clip-path is device pixel [2]. It's not easy to realize this and may be error-prone. So it'd be better to add a CSSPath, or use CSSPoint, or any other ways to make them clearer.
