Those are interesting arguments, but I don't quite understand them.

How is it less error-prone to call xcb_window_new rather than
xcb_generate_id? The former just calls the latter, and their type
signatures are identical. Since we no longer have compile-time type
checking here, I'd think it would be confusing that you can call
xcb_window_new and pass the result to xcb_open_font, even though doing
so would produce no errors at run-time.

Why is xcb_generate_id less likely to induce programmers to initialize
their variables than xcb_window_new? A decent compiler will catch such
errors anyway...
