The procedures described in this REF file implement the equivalent  Xlib
C functions for cursor management.

XCreatePixmapCursor(DspPtr,xid1,xid2,XColorPtr1,             [procedure]
                    XColorPtr2, uint1,uint2) -> ulong3
        Creates a cursor  out of its  component parts from  data in  the
        calling program. The cursor pixmap is specified by xid1 and  the
        mask pixmap  is  specified  by xid2,  XColorPtr1  specifies  the
        foreground  colour  and  XColorPtr2  specifies  the   background
        colour, and uint1 and uint2 specify the x and y co-ordinates  of
        the cursor's hot spot.


XDefineCursor(DspPtr,xid1,xid2)                              [procedure]
        The cursor specified by xid2, will be used when the mouse is  in
        the window specified by xid1.


XUndefineCursor(DspPtr,xid)                                  [procedure]
        XUndefineCursor undoes the  effect of  a previous  XDefineCursor
        for the window specified  by the xid. When  the mouse is in  the
        window, the  parent's  cursor will  now  be used.  On  the  root
        window,  with  no  cursor  specified,  the  default  cursor   is
        restored.


XFreeCursor(DspPtr,xid)                                      [procedure]
        The cursor specified by the xid  is destroyed. It should not  be
        referred to again or an error will be generated.


XCreateFontCursor(DspPtr,uint) -> xid                        [procedure]
XCreateGlyphCursor(DspPtr,xid1,xid2,uint1,uint2,             [procedure]
                    XColorPtr1,XColorPtr2) -> xid3
XRecolorCursor(DspPtr,xid,XColorPtr1,XColorPtr2)             [procedure]
XQueryBestCursor(DspPtr,xid,uint1,uint2,uintptr1,            [procedure]
                    uintptr2) -> int
        These procedures implement the  equivalent C functions.
