Gtk+ does have code that tries to resize a window if it did not get the size it 
requested.
Also, it does try to satisfy the size hints itself, which is wrong.  Hints are 
for the window manager to respect or ignore as it wishes.  It is nothing wrong 
with ignoring hints.  They are, after all, just that, hints.
This is an example why it doesn't work to do what Gtk+ does.  This is a major 
Gtk+ bug IMHO.
I'm afraid it is out of Emacs control.
