      Status XQueryBestTile(display, which_screen, width, height, width_return,
      height_return)
            Display *display;
            Drawable which_screen;
            unsigned int width, height;
            unsigned int *width_return, *height_return;

      Status XQueryBestStipple(display, which_screen, width, height,
      width_return, height_return)
            Display *display;

ARGUMENTS
      class     Specifies the class that you are interested in.  You can pass
                TileShape, CursorShape, or StippleShape.

      display   Specifies the connection to the X server.

      width
      height    Specify the width and height.

      which_screen
                Specifies any drawable on the screen.

      width_return
      height_return
                Return the width and height of the object best supported by the
                display hardware.

DESCRIPTION
      The XQueryBestSize function returns the best or closest size to the
      specified size.  For CursorShape, this is the largest size that can be
      fully displayed on the screen specified by which_screen.  For TileShape,
      this is the size that can be tiled fastest.  For StippleShape, this is
      the size that can be stippled fastest.  For CursorShape, the drawable
      indicates the desired screen.  For TileShape and StippleShape, the
      drawable indicates the screen and possibly the window class and depth.

      An InputOnly window cannot be used as the drawable for TileShape or
      StippleShape, or a BadMatch error results.

      XQueryBestSize can generate BadDrawable, BadMatch, and BadValue errors.

      The XQueryBestTile function returns the best or closest size, that is,
      the size that can be tiled fastest on the screen specified by
      which_screen.  The drawable indicates the screen and possibly the window
      class and depth.  If an InputOnly window is used as the drawable, a
      BadMatch error results.

      XQueryBestTile can generate BadDrawable and BadMatch errors.

      The XQueryBestStipple function returns the best or closest size, that is,
      the size that can be stippled fastest on the screen specified by
      which_screen.  The drawable indicates the screen and possibly the window
      class and depth.  If an InputOnly window is used as the drawable, a
      BadMatch error results.

      XQueryBestStipple can generate BadDrawable and BadMatch errors.

DIAGNOSTICS
      BadMatch  An InputOnly window is used as a Drawable.

      BadDrawable
                A value for a Drawable argument does not name a defined Window
                or Pixmap.

      BadMatch  The values do not exist for an InputOnly window.

      BadValue  Some numeric value falls outside the range of values accepted
                by the request.  Unless a specific range is specified for an
                argument, the full range defined by the argument's type is
                accepted.  Any argument defined as a set of alternatives can
                generate this error.
