Perhaps we could cons�der the following:

Non linear ZBuffer

-Clip plane goes all the way out, but the ZBuffer has different bucket
sizes:

eg

near resolution       |<< user defined watershed. far resolution
|||||||||||||||||||||||        |         |         |        |

new ZBuffer implmentation : ZBufferNonLinear perhaps

Or have a quick rendering cycle to draw the clipped components, then
another to draw the inside components on top. To make it faster, do not
use a ZBuffer, use some other system for these more distant surfaces
(back face cull, ZOrder render??).

I hope this is useful and not redundant,

Chris
