/*
 * Set the desired window to the box with the indicated boundaries.
 * All scrolling should only affect the area inside the window.
 * We currently ignore the last 2 args since we're only using this
 * for scrolling and want to use the feature on vt100's as well as
 * on concept 100's.  left and right are for future expansion someday.
 *
 * Note that we currently assume cursor addressing within the window
 * is relative to the screen, not the window.  This will have to be
 * generalized if concept windows are to be used.
