/**********************************************************************/
/* Gauge super class
/* Subclasses need to override
/* drawself should assume that the bitmap is correct
/* refreshBackground: should call display so we see immediately
/* sizeTo:: if they alter orientation
/*
/* Rev 0.x Works but other objects must look for overflow (subclass of View)
/* Rev 0.9 First revision that I started log for.
/* 11/24/89 Made this a control so it could do target action (per DS)
/*
/*
/* will notify target (via target/action) of any overflow
/* not all subclasses will use the title capabillity
/*
/*
/* for speed:
/* turn off autoscaling
/* set modulus tic = 0.0
/*
/* Bugs:
/* Overflow is not detected if the value is set and then scale changed
/* no way to autoscale and still have a cap
/*
/* AutoScaling:
/* Autoscaling with no labels will cause the number of tics to change.
/* when blowing up or shrinking tic mark values otherwise...
/*
/* This will rescale the tic marks or start values under thse rules
/* Underrun:
/* if .aThreshLo > 0.0
/* then move low point so we are centered
/* else if aThreshHi < 1.0
/* then rescale tic marks to blow up
/*
/* Overrun
/* if .aThreshHi < 1.0
/* then move the tic marks to shrink
/* else if .aThreshLo > 0.0
/* then move up low so this is centered
/*
