Details:

The figure properties 'windowkeypressfcn' and 'windowkeyreleasefcn' are only
implemented to the extent that you can modify the property values.  There is
no actual backend implementation for the Qt or FLTK toolkits.

What should happen is that the 'windowkeypressfcn' gets called whenever there
is a keypress event in the window, even when another child object like a
uicontrol has a keypressfcn set.  Some explanation is here:
http://stackoverflow.com/questions/25174400/matlab-difference-between-keypressfcn-and-windowkeypressfcn.

I'm attaching a test script tst_keypress.m.  Call it with no arguments to see
how the keypressfcn callback works.  Then do 'close all' and call tst_keypress
(true) to run the windowkeypressfcn callback and see that nothing happens.

It's pretty obvious that there is no backend because I used 'grep -i
windowkey' on Canvas.cc and __init_fltk__.cc and found nothing.  Those are the
two files that need to be updated to support this.
