[PyMOL] setting a ray resolution then outputting a png doesn't always work

[Sabuj Pattanayek]

Hi,

I set smooth lines from the menu, then I did:
set orthoscopic=1
set antialias=1
ray 1200,1200
png file.png

and file.png was the same size as the display window (less than 
1200x1200), and I could still see jagged lines, as if it outputted 
exactly the quality seen in the display window. I got this to work once 
with a different pse file, tried restarting pymol but I can't get it to 
work anymore. I'm using 0_98beta27 on linux.

Thanks,
