Easier than that, it is already calculated, all you have to do is output 
the depth values instead of calculating textures and lighting. I did 
this as one of my earliest patches, Ron Parker did a similar patch, and 
the post_process patch in MegaPOV had a fiilter that output the depth 
data, though it didn't skip the texture and lighting calculations.

The post_process patch wasn't ready for an official release, and it 
would be pointless to add one of the other implementations when it would 
only get replaced with something else in the future.
