I want to draw a circle in a Glyph. I can't seem to figure out the
semantics of the 'curve' Canvas call to draw a circle, and don't see
any other way of doing it from a Glyph.

Btw, are Glyphs the appropriate level for constructing small
widget-like things in 3.0? I don't care about backwards compatibility;
however, I don't see how Glyphs & Unidraw interact, and I see several
problems that indicate I'm missing something (like, if a glyph updates
a value asynchronously, how do you tell all Canvas's using that Glyph
that this has occured?)

thanks
