Re: [PyMOL] Labeling CGO objects

Ron,

CGO labels are currently insufficient and need work.  Right now, the only
way to access high-quality labels (using scalable TrueType fonts) is to
create fake atoms and then label them.

Cheers,
Warren

PS.  As a minor correction of fact, dashes aren't drawn with CGOs -- they're
hard-coded at the C level as measurement objects.
