For some Gnome desktops, the look and feel of the tooltips is patched in to the 
libGtk+ library and not accessable if you compile Emacs without Gtk+.  This is 
not the standard libGtk+, it is a patched version, patched by Ubuntu or Fedora 
or some other distribution. Things like transparency and fore/background colors 
are hardcoded into the library.  So volunteers does not help.
