/* The resizelgwin routine updates the line graphics window in response to a */
/* ConfigureNotify event. */
/* Sam Southard, Jr. */
/* Created: 29-Mar-1991 (from figdisp/resizewin) */
/* Modification History: */
/* 2-Apr-1991 SNS/CIT Modified to use a Pixmap the same size as the window, */
/* instead of always having a LG_MAX_xxx sized pixmap. */
/* 8-Oct-1991 SNS/CIT Globals now in globals.h */
/* 11-Feb-1992 SNS/CIT Elimincated some unnecessary code. */
/* 14-Feb-1992 SNS/CIT Now clears the line graphics window to lg.pix[0] */
/* instead of BlackPixel */
/* 10-Apr-1992 SNS/CIT No longer uses minimum or maximum window sizes. Now */
/* uses lg.imwidth & lg.imheight as the width & height */
/* of the pixmap. */
/* The program include files */
#include "figdisp.h"
#include "globals.h"
