Subject: [Bf-python] Draw.RegisterEvent proposal

Not trying to dissuade you, *really*, but as this touches parts outside
bpython, actually the main event loop, it needs to be discussed at the
bf-committers list too, starting with a simple proposal, with examples of
usage.  There people not necessarily know about Draw.Register, etc. so the
proposal should be more general, about the functionality itself and what it
could be good for.

That's how it happens always -- Ton would eventually ask you for this.  And
let me warn that most times it's not as fast as the coder would like.  Your
idea is a good one, we all just need to discuss, get suggestions from all
about possible uses and the best way to implement it.

Since the code for scriptlinks is already in place and has a straightforward
interface, I suggest we start there, there can be more scriptlink event
types.  And it's easy to set them from scripts now, too.

Object scriptlinks on redraw might be enough for this particular example, or
not?
