Oh, and don't anyone be fooled by this name, which merely implies the manner in which number values behave during a warparound. WRAPAROUND axes, when they wraparound, skip to the other extreme value. EXACT axes, when they wraparound, merely have their values decrease again. A lovely little puzzle this spinning rock. --adrian ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
