You need to set the allowShellResize resource on the toplevel shell widget
to true.  Presumably, the reason for this resource is to avoid excess
geometry negotiation with a window manager and possibly surprising results
of the application changing it's size once the window has already been
created.  That resource won't affect user-requested changes in size (via
the window manager), but will affect the program's ability to change
it's toplevel window once the window has been realized.  For efficiency
reasons, it's best to do as little geometry negotiation as possible after
the realize (move as much as possible before the realize), but there are
times when this is impractical or impossible.
