Subject: Use more reliable X-call for getting window position
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=c6dc8d81c81b393e2de7eaebd356966db34c2008

Use more reliable X-call for getting window position

XtGetValues on XtNx, XtNy is unreliable. XGetWindowAttributes seems
to give more reliable results, and automatically accounts for the width
of window dressing. The -frameX/Y options are no longer needed bcause
of this, and were removed.
