That's actually not that difficult to implement. (I think).

Jmol now just renders two images, assuming into the same bitmap. It would just 
have to put pixels in different columns! Only thing is that Jmol needs to 
figure out if the first Jmol bitmap buffer column is a even or uneven column 
on screen... and correct for this by either taking +5 or -5 angle.

I've seen in the doc demo that resolution was low resulting in having a harder 
time to focus on the 3D image... anti-aliasing helps here... but I assume 
that g3d can still apply antialiasing to each frame separately...
