I'm quite far from an xlib expert; but I do have volume 1 of the
O'reilly series handy...

Drawables consist of windows and pixmaps (offscreen memory regions you
can draw to).  You can safely specify a Window or Pixmap anywhere
Drawable is expected as argument (they're all integer types, so no
nasty, unsafe casting required).

Displays hold information about an X server and its screens.  Think of
the common "-display" option in X apps.  The Display type is a struct,
whereas (as already mentioned) Window, Pixmap and Drawable are int
