Most important to me, using TTF forces you to use text metrics 
arguments, when you're actually doing graphics and text metrics are 
maningless here.

Yes. We need to add support for the rest of the commands. It is in my 
ToDo list now.

You're right. Just pushed 2 updates for that. We never actually needed 
literal Float64Arrays anyway.

Just pushed your IconMorph as an update. Included this as a class
