We noticed while reviewing internal test cases for border-radius that
Gecko permits <percentage> values for all border-radius properties,
contra the spec which allows only <length>.  This has been the case for
probably as long as Gecko has implemented any sort of curved border
corners.  Percentages are taken as relative to the width of the
border-box (not the content-box) to which the style applies.

What do y'all think of adding this extension to the spec?  As far as I
can tell, no other implementation has this already, but it should not
pose any serious difficulty either in the parser or the renderer.
