/* Sam Southard, Jr. */
/* Created: 13-Mar-1991 (from figdisp/initwins) */
/* 31-Jul-1991 SNS/CIT Now uses the visual member of the wininfo structure */
/* 15-Aug-1991 SNS/CIT No longer includes hooks for vista */
/* 6-Sep-1991 SNS/CIT Changes from SSL::TENNANT implemented */
/* 19-Sep-1991 SNS/CIT Now uses the Keck icon */
/* 3-Oct-1991 SNS/CIT Now initializes zfac structure member */
/* 8-Oct-1991 SNS/CIT Globals now in globals.h */
/* 10-Oct-1991 SNS/CIT Window manager hints now in initwmattr */
/* 22-Oct-1991 SNS/CIT No longer sets the border pixel */
/* 25-Nov-1991 SNS/CIT X and Y zoom now separate */
/* 29-Jan-1992 SNS/CIT Modifications for the Keck data acquisition system */
/* folded in. */
/* 11-Feb-1992 SNS/CIT Now looks for pointer motion masks */
/* 14-Feb-1992 SNS/CIT Now clears the pixmap to lg.pix[0], not BlackPixel. */
/* Now includes the id in the title */
/* 24-Feb-1992 SNS/CIT Visual allocation now done in the getvisuals routine */
/* 26-Feb-1992 SNS/CIT Cursor scaling offsets initialization added. */
/* 6-Apr-1992 SNS/CIT Now uses a blank cursor so that we can have large */
/* crosshairs as our cursor */
/* 8-Apr-1992 SNS/CIT Now has a better title for Keck version */
/* 10-Apr-1992 SNS/CIT No longer uses minimum or maximum window widths. Now */
