A bit of trivia:

You can stack visual effect commands so that you get a series of effects.  A 
good example is this:

visual effect dissolve to inverse
visual effect dissolve

Check it out and see what happens.  The important questions are, is there a way 
to turn off any visual effects that are queued, and can you tell if and/or 
what visual effects are queued?

Why do I care, you may ask?  I wanted to put a handler in my Home stack that
would detect arrow key events and queue an effect for them, since they don't
have any nice effect by default.  Well, that's where I found out that effects
are cumulative.  I would like a string returned that tells what effects are
queued, like "wipe slow to black, dissolve to inverse, scroll up" for that
list of effects.  That wouldn't be too hard would it?  This way I could even
trap effects I don't like.  Isn't that what object programming is all about?
