[Radiance-general] Misplaced Rendering Frame

[Greg Ward]

Hi Nick,

I have no idea what was causing this, but Jack de Valpine said offline  
he's seen similar issues with rpiece and image sections (pieces) that  
have very little going on, like the corners of your image.  It may be  
a race condition that the NFS lock manager isn't handling properly,  
but nothing I can really do much about.  I don't know how the ambient  
resolution would affect this, so it's a puzzle.  It could just be  
coincidence.

In related news, I just made an enhancement to the "rad" executive  
program to run rpiece automatically when -N is set >1 and only a  
single view is being requested.  It even does automatic recovery if  
the rendering gets interrupted.

Best,
-Greg
