Gameclock max_fps bug.

[rdeaton]

When you set max_ups > max_fps, the effective fps cap seems to end up being the same.

To reproduce, add the following lines to skel.py in the Scene's init
self.clock.max_fps = 30
self.clock.max_ups = 60

I don't know if it's the same but I can't seem to reduce the fps using macfps or maxups in director.init , it always seems to be 30 fps. On XO 1.75 fps is healthy 29, but there is a heavy delay on startup and also on scene transition.
