/****************************************************************************
 * Name: nxtk_toolbarbounds
 *
 * Description:
 *   Return a bounding box that contains the toolbar in the coordinates of
 *   the containing, framed window.  For example, the recturned  origin
 *  (rect.pt1) is the offset toolbar in the framed window.
 *
 *   NOTE: This function is unsafe in the case of the multi-user NX server
 *   where the width of the window may be being changed asynchronously!  It
 *   may return the old size in this case.
 *
 * Input Parameters:
 *   hfwnd  - The handle returned by nxtk_openwindow
 *   bounds - User provided location in which to return the bounding box.
 *
 * Returned Value:
 *   OK on success; ERROR on failure with errno set appropriately
 *
