clipLinearMapToInterval Method

Clip this range to a linear half space condition

• if limitA > limitB the limit space is empty
  • make this range null
  • return false;
• otherwise (i.e limitA <= limitB)
  • solve a + u * f = limitA' and a + u * f = limitA`
  • if unable to solve (i.e. u near zero), a alone determines whether to (a) leave this interval unchanged or (b) reduce to nothing.
  • the f values are an interval in the space of this Range1d
  • restrict the range to that interval (i.e intersect existing (low,high) with the fraction interval.
  • return true if the range is non-null after the clip.
