Phil,
Thank you for trying it that deep. I confess that I have never seen
it working on emergency evaluators, although I don't be surprized.
The glyphMap should be honored in
TTCFont>>displayString:on:from:to:at:kern:. Then what needed would be
to "copy" the font (in the current version, #copy and friends are
overridden so it might have to be changed), and set up the
characterToGlyphMap method appropriately.
Other than this what I want to have is a way to "add" new size of
font easily. The interface I'm thinking is to add a menu item in the
"font" halo to add new size.
Thanks for the report. It is helpful,
