From 8af7dabe98dace1b5fefb9be63b5d15e2a31846a Mon Sep 17 00:00:00 2001

Subject: [PATCH] [#108] also moved the fps counting to the debugPanel

FPS information is now only available through the debug panel object
(and not anymore through the HTML element)

(Only one left now : me.debug.renderCollisionMap!)
