They're in pixels. However widget->allocation is only filled in when
the widget actually goes through the request/allocate process, it
isn't magically kept up-to-date at all times.

Look at how containers work, you need to emulate that. (If you're
using GnomeCanvasWidget in principle it does this. But note that the
request/allocate is normally done in an idle handler for efficiency.)
