[css-masking] clip-path: path()

I would like the clip-path: property[1] to actually support bezier paths (as a naive interpretation of the property name would have you expect).

The syntax would be a path function with an SVG-style path as a string, for example:

clip-path: path("M10 10 H 90 V 90 H 10 L 10 10”);

The units wold be interpreted as CSS pixel units, relative to the origin of the geometry box. Paths would be animatable, following the same rules as SVG.

I have a work-in-progress patch to add support for this to WebKit[2].
