        This is an easy one (at least for me). BadCursor is a protocol
error from XCreateWindow or XCreateSimpleWindow. What is probably
happening is that the window attributes mask argument specifies CWCursor
but that the actual .cursor element of the attributes structure is
not being initialized before the call.
        The appropriate solution in this case is to
#include <X11/cursorfont.h> and then set
<WindowAttributes>.cursor = XCreateFontCursor(display,cursor_shape) where
cursor_shape is one of the cursor type constants defines in cursorfont.h.
The <WindowAtributes> structure is the last argument passed to
XCreateWindow, the attributes mask is the next to last argument.
