[patch] gdk goes to 1 bit screens

["Shawn T. Amundson" <amundson CompleteIS com>]

Hello,

This is a patch for gdk that allows you to run at least most
of testgtk and gzilla (and probably a bunch of gnome apps) on
1 bit displays.  I have only tested this a limited amount, but
know this is what does not work on 1 bit displays after this 
patch:

gtkpreview, though with some comments it can be made silent to allow
            you to pop it up -- specifically the check or # of avail
            colors.
GIMP, even after the above is working, because of pixmap code for
      the toolbar (and probably lots more reasons, that's as far as
      I got today)

Some stuff is funky in gtk on B/W, but works way better then I 
thought it would considering the simplicity of this patch.
