It's true. The only way to get really nice transparent effects
from ldglite is to use the trick described here where you render at
a higher resolution and then scale down.

I believe the current model of the month at ldraw.org was rendered
with this technique, and it even has a "plate 1 x 1 round" in
transparent orange, if you want to check it out.

It'd be really cool if lpub had an option to do that for you though.
I wonder if you can force it to scale up through the ldglite options
box without totally messing up lpub...
