oriscus (& reversus) cavum

[eroux]

I recently got a small request from Antiphonale Monasticum project: the possibility to typeset empty oriscus and oriscus reversus, on the same model as the punctum cavum we currently have.

I'll give this a shot, but if my font-editing capabilities fall short of my aesthetic sense, I will hand it back.

I don't think much aesthetic sense is necessary here. To draw the hole, I usually use uniform scaling transformation, trying a few different values in order to get the lines to have the "normal" width (meaning the width of the joining lines, but it's the same as the lines in punctum cavum)

[henryso]

I'm not disagreeing. I'm just saying if I cannot come up with something that (to me) looks nice, then I'll hand this back to someone who is better at editing fonts.
