The CSSOM View spec is finally defining a set of
coordinate-transforming functions for converting between points
relative to various boxes, getting rects/quads from elements relative
to some other box, etc.  These'll apply to SVG as well, obviously, and
should help solve this problem in a generic fashion.

Just allow units in the viewBox definition, and then use the vw/vh
units, which are percentages of the viewport.
