Export performance data to be accessible in v8 #2

We need frame rate (I believe that is already available in the engine), but most importantly we need texture transfer bandwidth utilization (in Mb/sec).

Every time a texture rect is copied, the byte size of this rect should be added to a counter and every frame rendered this counter has to cumulate & reset. Then cumulative value per second should be available as a part of the profile object.

Accumulation can be done in the main rendering loop using timestamps. When duration of frame rendered passes, take total MB/duration_passed.

I plan to add a property Engine.perfCounters that will be an object with following attributes:

make it textureTxRate[] = [ actual, 5 sec average, 30 sec average]

what about Engine.profileData? or Engine.profileStats or simply Engine.profile?
