Nobody responded to my comments, so I took a closer look at the
code, and at X documentation on how to do keysym translation.
I found several problems with the gdk code:
* Keysym translation when Num Lock is on is broken.
* It fails to determine the keysym for the Lock modifier, which
should be used to distinguish between Shift Lock and Caps Lock.
* Even with the previous problem fixed, translation in the Caps
Lock case is incorrect.
I am working on a patch which attempts to correct these problems.
In addition, I found that the Sun X server does Num Lock handling
in a non-standard way. Normally, the keysym to use for a keypad
key when Num Lock is on is the second element in the array for that
keycode; however, in the Sun implementation, it is the third element.
(I verified that the version of XLookupString() in the Openwindows
X library functions accordingly). As far as I can tell, the only
feasible way to deal with this is to hack the code to determine
whether it is dealing with a Sun X server.
