Detailed Description

Author: ????-??-?? Unknown

History:

2011-04-25 Steven Lambright - Fixed a problem where 1 too few lines were being read

2015-06-30 Makayla Shepherd and Ian Humphrey - Modified stop() to keep the viewport buffer object from reading an extra line at the bottom of the viewport rectangle. This could potentially cause a crash from reading outside of the bounds. Fixes #2171.
