Hi Anders,

I just draw a filled transparent GsBOXF over the top of what ever image
I want to fade, but I use the subtraction semi-transparency mode.  So if
I want to fade up from black, I set the rgb of the box to (255,255,255)
to subtract all colour from the frame, and then decrement the rgb every
subsequent frame to ramp it up.  Be sure to set the priority higher than
the every thing else in the OT as well.

Cheers

Jim
