I think a problem with that is it's interaction with things like valgrind.
Setting 'int w = *width;' may complain that it's using uninitialized memory
if the user hasn't initialized it yet, and then setting it back on failure
won't cause an uninitialized memory warning if apps try to use it after
failure.
