The problem, again, is that the Page Visibility definition was only done 
that way because I was told it would NOT be used for things like this. 
The Page Visibility definition is useful for being able to deal with 
media playback (which is not intrinsically tied to "visibility" in the 
case of audio, for example, but may well be tied to "attention", which 
is more what Page Visibility tries to capture).

I would like to object to using the Page Visibility definition of 
visibility for requestAnimationFrame, yes.
