XReparentWindow()'s documentation says "...if the specified window was
originally mapped, the X server automatically performs a MapWindow request on
it."

so,wondering whether you'll indulge me and run a test (somewhere under the 'jr
causing trouble' directory. :-)) with a new command-line option.

I looked at xterm code.  the '-into' arg is converted (strtol()) and cast to
Window type.  it is passed to 'misc.c:xtermEmbedWindow', where it's used as
third arg in XReparentWindow.  I also looked at your 'disp_x11.cpp', the
XMapWindow call in line 429.  so, why not try and place a call to
XReparentWindow in line 430?  I've attached a simple Tk UI which provides a
800x600 frame[*] and outputs its window id to stderr.  if you can get that into
povr?!

[*] can easily be changed in line 12.

of course it's a hack, and probably will "flicker" once as it would be unmapped
immediately after line 429, but hey..

didn't the Sex Pistols sing "I don't know what I want, but I know how to get
it"?  :-)
