          count_return)
                Display *display;

          BitmapBitOrder(display)

          BitmapPad(display)

          BitmapUnit(display)

          DisplayHeight(display, screen_number)

     ARGUMENTS
          display   Specifies the connection to the X server.

          count_return
                    Returns the number of pixmap formats that are
                    supported by the display.

          screen_number
                    Specifies the appropriate screen number on the
                    host server.

     DESCRIPTION
          The XListPixmapFormats function returns an array of
          XPixmapFormatValues structures that describe the types of Z
          format images supported by the specified display.  If
          insufficient memory is available, XListPixmapFormats returns
          NULL.  To free the allocated storage for the
          XPixmapFormatValues structures, use XFree.

          The ImageByteOrder macro specifies the required byte order
          for images for each scanline unit in XY format (bitmap) or
          for each pixel value in Z format.

          The BitmapBitOrder macro returns LSBFirst or MSBFirst to

          indicate whether the leftmost bit in the bitmap as displayed
          on the screen is the least or most significant bit in the
          unit.

          The BitmapPad macro returns the number of bits that each
          scanline must be padded.

          The BitmapUnit macro returns the size of a bitmap's scanline
          unit in bits.

          The DisplayHeight macro returns the height of the specified
          screen in pixels.

          The DisplayHeightMM macro returns the height of the
          specified screen in millimeters.

          The DisplayWidth macro returns the width of the screen in
          pixels.

          The DisplayWidthMM macro returns the width of the specified
          screen in millimeters.

     STRUCTURES
          The XPixmapFormatValues structure provides an interface to
          the pixmap format information that is returned at the time
          of a connection setup.  It contains:
          typedef struct {
               int depth;
               int bits_per_pixel;
               int scanline_pad;
          } XPixmapFormatValues;
