Re: Some issues



Jon,

Personally, typeset math is the main reason for using the metapost
plugin and why I originally wrote it, so I agree that braces and
underscores should not be escaped.  However, since you didn't enclose
your expression in $ $ to produce inline math, braces act to group and
underscores are not permitted and need to be expressed as \{ \} \_. 
Your labels did not contain $ and the braces and underscores were plain,
so I couldn't determine what you were trying to do. That's all.

At any rate, I'm also going to work on getting the font scaling correct
too.  I'm not certain where else it's deficient.
