Hi,

Although it's interesting to be able to save a zbuffer, this feature is  
ahead of what I think we should implement right now... the render code  
at this moment delivers a very complex 'Render Result' structure, which  
can hold an unlimited amount of layers, passes and - in future - sample  
buffers. There is no single zbuffer anymore...

All these buffers should be manageable, editabe, viewable or saveable  
in some way. I want to look at a way to make that easy to access in  
future, which might make this patch become obsolete or differently  
accessed. :)

It's also a feature request I don't know what it's useful for... to  
make B&W masks for painting programs or so? Right now, the purpose is  
to use the compositor system for control over render buffers... it can  
remap floating point zbuffers nicely. I also dropped integer zbuffers,  
defaulting to only floating point 'camera distance' bufffers. Your code  
still uses the integer zbuffers somehow... but how it works?

Last note;

writeimage.c
pixf[0] = pixf[1] = pixf[2] = pixf[3] =  
1-rres.rectz[pixel]/100000000000;

This is quite invalid code... check the compiler warning. :)

Sorry for not having time to write the design docs & schedule I have in  
mind for the render project... your help is very welcome. :)
