I'd like to suggest that instead of attempting to band-aid a fix for
lame C typechecking that we just give up and recognize that XIDs are
32-bit values (with the top three bits zero). The alternative is to
require miles of type conversion code where none should be required
(window->drawable). I suggest that of all the soures of error in an X
program, mixing objects of different types is a relatively rare
occurance, certainly not warranting this kind of pain.
