We could've folded that whole hash into something in the XS code, but it would
not actually have saved any memory usage.  At least with the giant hash in a
separate file, you don't have to load it if you don't need it.

The code in Keysyms.pm is generated at build time from gdkkeysyms.h.  Since
gtk+ is API-stable, i would have to imagine that the values of the keycodes
cannot change.  I don't know if that extends to using the exact same keycodes
for X and Win32, but if you only need a few keycodes, you ought to be safe
creating your own mapping for just those.

Officially:  I do not endorse this duplication, as it is duplication and i'm
not convinced you'll actually save much memory.
