Summary: Photo visibility in widgets

Initial Comment:
Hi,
we wrote an extension in C to Tk for aMSN which let us
to load animated gifs and we display each frame after a
delay with Tk_PhotoPutBlock. But when we have many
animated GIFs loaded it take many CPU power and we
would like to reduce it. To do that we would need a
function to know the visibility of the image. Not if it
is bind to a widget but if it is displayed in any
widget. Or maybe you have another idea to know that...
Thanks
