* I'm going to try to explain, as I understand it, why we
* have to do XGetWMNormalHints and XSetWMNormalHints here,
* although I can't guarantee that I've got it right.
*
* In a correctly written toolkit program, the Shell widget
* parses the user supplied geometry argument. However,
* because of the way xterm does things, the VT100 widget does
* the parsing of the geometry option, not the Shell widget.
* The result of this is that the Shell widget doesn't set the
* correct window manager hints, and doesn't know that the
* user has specified a geometry.
*
* The XtVaSetValues call below tells the Shell widget to
* change its hints. However, since it's confused about the
* hints to begin with, it doesn't get them all right when it
* does the SetValues -- it undoes some of what the VT100
* widget did when it originally set the hints.
*
* To fix this, we do the following:
*
* 1. Get the sizehints directly from the window, going around
* the (confused) shell widget.
* 2. Call XtVaSetValues to let the shell widget know which
* hints have changed. Note that this may not even be
* necessary, since we're going to right ahead after that
* and set the hints ourselves, but it's good to put it
* here anyway, so that when we finally do fix the code so
* that the Shell does the right thing with hints, we
* already have the XtVaSetValues in place.
* 3. We set the sizehints directly, this fixing up whatever
* damage was done by the Shell widget during the
* XtVaSetValues.
*
* Gross, huh?
*
* The correct fix is to redo VTRealize, VTInitialize and
* VTSetValues so that font processing happens early enough to
* give back responsibility for the size hints to the Shell.
*
* Someday, we hope to have time to do this. Someday, we hope
* to have time to completely rewrite xterm.
