Yes, the X11 package is woefully incomplete -- hence the existence of
X11-extras.

My general strategy when I want to implement something, but don't
know which xlib calls are needed:

1.  Find some source that accomplishes a similar task (dwm is a great
candidate, it has very nice code)

2.  Notice which xlib functions are called

3.  grep X11 to see if these calls are implemented

4.  If 3 is unsuccessful, read the man pages and write some FFI for
X11-extras.
