If a level-of-detail metric could be added to the conditions used
for <switch>, then images and any geometry could be used for LOD
display.  This would allow multiImage/subImage/subImageRef to be
replaced with appropriate use of <g> and <image>.

One possible LOD metric might be the ratio of userspace
coordinate units to device pixels.

An example of how this might appear:

<switch>
  <image width="360" height="240" xlink:href="m8.jpg" max-lod="2"/>
  <image width="360" height="240" xlink:href="m4.jpg" min-lod="2" max-lod="4"/>
  <image width="360" height="240" xlink:href="m2.jpg" min-lod="4" max-lod="8"/>
  <rect width="360" height="240" fill="#ff0000" min-lod="8"/>
</switch>
