Ok, I'm a little confused here. The way I understand it is that sprites with any alpha, even 0, will be rendered. Sprites with _visible == false are not rendered. Correct so far? As far as processing (aside from rendering), any jpg or other compressed format has to be processed--it has to be decompressed before it can be rendered. Is an invisible (_visible == false) sprite decompressed? Or is the Flash engine smart enough to look at the _visible flag, and skip the decompression? You could have a movie clip sprite with a dozen jpegs in it, or more. I hope that Flash doesn't decompress them all if the movie clip is not visible. I'm not quite sure what's going on under the hood there.
