    DESCRIPTION
         The AllPlanes macro returns a value with all bits set to 1
         suitable for use in a plane argument to a procedure.
    
         The BlackPixel macro returns the black pixel value for the
         specified screen.
    
         The WhitePixel macro returns the white pixel value for the
         specified screen.
    
         The ConnectionNumber macro returns a connection number for
         the specified display.
    
         The DefaultColormap macro returns the default colormap ID
         for allocation on the specified screen.
    
         The DefaultDepth macro returns the depth (number of planes)
         of the default root window for the specified screen.
    
         The XListDepths function returns the array of depths that
         are available on the specified screen.  If the specified
         screen_number is valid and sufficient memory for the array
         can be allocated, XListDepths sets count_return to the
         number of available depths.  Otherwise, it does not set
         count_return and returns NULL.  To release the memory allo-
         cated for the array of depths, use XFree.
         The DefaultGC macro returns the default GC for the root win-
         dow of the specified screen.
    
         The DefaultRootWindow macro returns the root window for the
         default screen.
    
         The DefaultScreenOfDisplay macro returns the default screen
         of the specified display.
    
         The DefaultScreen macro returns the default screen number
         referenced in the XOpenDisplay routine.
    
         The DefaultVisual macro returns the default visual type for
         the specified screen.
    
         The DisplayCells macro returns the number of entries in the
         default colormap.
    
         The DisplayPlanes macro returns the depth of the root window
         of the specified screen.
    
         The DisplayString macro returns the string that was passed
         to XOpenDisplay when the current display was opened.
    
         The XMaxRequestSize function returns the maximum request
         size (in 4-byte units) supported by the server without using
         an extended-length protocol encoding.  Single protocol
         requests to the server can be no larger than this size
         unless an extended-length protocol encoding is supported by
         the server.  The protocol guarantees the size to be no
         smaller than 4096 units (16384 bytes).  Xlib automatically
         breaks data up into multiple protocol requests as necessary
         for the following functions:  XDrawPoints, XDrawRectangles,
         XDrawSegments, XFillArcs, XFillRectangles, and XPutImage.
    
         The XExtendedMaxRequestSize function returns zero if the
         specified display does not support an extended-length proto-
         col encoding; otherwise, it returns the maximum request size
         (in 4-byte units) supported by the server using the
         extended-length encoding.  The Xlib functions XDrawLines,
         XDrawArcs, XFillPolygon, XChangeProperty, XSetClipRectan-
         gles, and XSetRegion will use the extended-length encoding
         as necessary, if supported by the server.  Use of the
         extended-length encoding in other Xlib functions (for exam-
         ple, XDrawPoints, XDrawRectangles, XDrawSegments, XFillArcs,
         XFillRectangles, XPutImage) is permitted but not required;
         an Xlib implementation may choose to split the data across
         multiple smaller requests instead.
    
         The LastKnownRequestProcessed macro extracts the full serial
         number of the last request known by Xlib to have been pro-
         cessed by the X server.
         The NextRequest macro extracts the full serial number that
         is to be used for the next request.
    
         The ProtocolVersion macro returns the major version number
         (11) of the X protocol associated with the connected
         display.
    
         The ProtocolRevision macro returns the minor protocol revi-
         sion number of the X server.
    
         The QLength macro returns the length of the event queue for
         the connected display.
    
         The RootWindow macro returns the root window.
    
         The ScreenCount macro returns the number of available
         screens.
    
         The ScreenOfDisplay macro returns a pointer to the screen of
         the specified display.
    
         The ServerVendor macro returns a pointer to a null-
         terminated string that provides some identification of the
         owner of the X server implementation.
    
         The VendorRelease macro returns a number related to a
         vendor's release of the X server.
