Subject: Interleaved gradient noise is now parameterized by frame count

I'm using an AAP (vrc.school/docs/Other/AAPs/) to create a frame
counter. That frame counter then drives this parameter. Thus the sparkly
pattern won't turn into gross flashing when the framerate is low.

Also add a speed parameter to control IGN.
