Thank you very much for the feedback. I'm glad you like it.
I looked at 30187c02.dat, but I didn't see any problems. What part of it is
the wrong color? I'll take a look, and see about tracking down the problem
and fixing it before the next build.
I'm a little puzzled about the memory usage, though. Conditional lines will
consume memory, but I would expect them to consume approximately twice as
much memory as a comparable number of standard (type 1) lines. I'll have to
look into it. It is worth noting that conditional lines do slow down the
rendering rather significantly, even without disk swapping. However, it
shouldn't be anywhere near a factor of 25.
Also, while the conditional lines have to be loaded in order to be used for
smoothing when that option is enabled, it occurs to me that I could then
delete them from memory if they aren't set to be drawn, as they serve no
further purpose. I'll look into that as well.
