Using percentage coordinates for vector images is awkward. Perhaps 
adding an attribute to the AREA element that specifies the coordinate 
system used? Something like SYSTEM or COORD-SYSTEM?

  <AREA SYSTEM="pixel" COORDS="0,0,100,100">
  <AREA SYSTEM="percent" COORDS="0,0,100%,100%">
  <AREA SYSTEM="cartesian" COORDS="-1.0,-1.0,1.0,1.0">
  <AREA SYSTEM="vector" COORDS="0,0,1.0,1.0">

These could be easily implemented. If no system is defined, the browser 
could determine if the type is "pixel" or "percent". Eventually "polar" and 
various three-dimensional (cube, sphere) could be added.
