I'll strip the code down later/tomorrow so I can test it -
initialising to zero sounds like a promising candidate though - it
does indeed check to see if the value has changed.
One thing I did notice in there was that it used functions to get the
max and min value, seems to me even just buffering these values would
offer a slight performance increase - negligible granted, may changes
like this across the board would make haiku even zippier than it
already is!
