       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.
