I may be totally clueless here, but..
> SHAPE=RECT COORDS="0, 0, 50%, 100%"
... I think there is no real need for % values. The coordinates can
always be given in absolute relative to the images real size, as is
normal now. If client decides to scale the image, it is trivial to
compute the new coordinates.
Or, is someone seeing some use for the % use in image map creation
