Thanks, Jason. My drawing needs are pretty rudimentary. A music editor
doesn't need much more than the ability to draw lines and characters. A
nice addition would be antialiased curves such as Qt offers but that is
optional. A so-called "canvas" sometimes offers optimized drawing updates,
so the editor doesn't have to redraw the entire page if one portion of it
changes. That is not strictly necessary, and in fact it wouldn't be hard to
implement a bit of that functionality myself.
