[pygame] "fade to"?

[Terry Hancock <hancock@xxxxxxxxxxxxxxxxxxxx>]

I've been working with PyGame for a bit now.  One thing that
is pretty annoying is the lack of smooth volume adjustment
in pygame.mixer.

There's a "fadeout" method for Sound objects, but nothing
that allows a smooth transition from one volume to another
AFAICT.  I can transition the sound sharply from one volume
to another, but it causes an audible "pop" effect.

I'd prefer to do something like a 0.1 to 0.5 second smooth 
fade from one level to the other.  This would be 
particularly useful for "shaping" background music to 
accomodate dialog in a game.

Is there a way to achieve this effect?

Cheers,
Terry
