Gee, I had totally forgotten that look_at straigthens the up and right 
vectors.

Thanks!


Now I remember also to wonder : why ? I believe it is the only case 
where Pov tries to 'smartly' correct what the user specifies... and 
destroy my careful camera shearing. (BTW and IIRC, one need to disable 
vista buffers to use camera shearing.)


Povingly,
