-geometry specification for gtk_init

["Adam P. Jenkins" <ajenkins cs umass edu>]

I couldn't find this in the mailing list archive or FAQ, so..
gtk_init doesn't seem to support the -geometry command line option, or
anything equivalent.  Is there any equivalent way to specify the
toplevel geometry at startup, as opposed to compile time?  Even by
config file, etc., short of implementing it myself?

I ask, because this is the only X toolkit I've seen that didn't
support -geometry; it's even specified in the X standard as an option
that all X programs should support.  Was it left out of gtk
deliberately, or is this just something that needs to be implemented
still?  If the latter, I can submit a patch to gtk_init to parse this
option, but I figured I'd ask if there's a reason it's not there
first.
