Accept reads events, which include the map notify and initial exposure.
For interactors, you probably need an event-reading loop that waits
until the interactor's canvas is mapped.  A somewhat simpler approach
for glyphs is to have a monoglyph that detects when it is first drawn.
Note that without some form of concurrency, a non-interactive dialog box
won't respond correctly to exposures after being first drawn because
the computation won't be interrupted to handle the redraw.
