/*
 * Note: this piece of code was tested on Win95 platform before being ported onto
 *   UNIX. Some problems on both platforms still lingering and are worth being
 *   mentioned here:
 *   On Win95, the toolbar customize dialogbox is created using DialogBoxParam()
 *   with Toolbar handle passed as parent. But somehow it doesn't work ( GetParent()
 *   against the dialogbox always returns the toolbar's parent instead of the
 *   handle of toolbar itself. As a workaround, Toolbar handle is passed as 
 *   lParam and on initialization, the toolbar customize dialogbox stores it 
 *   away as a window property.
 *   On LINUX, GetProp ( I also tried GetWindowLong vs. SetWindowLong and would
 *   have the same trouble ) would frequently fail inside WM_MEASUREITEM handler
 *   if the two listboxes of the custom dialog have style set to LBS_OWNERDRAWFIXED.
 *   To the contrary, if they are set to LBS_OWNERDRAWVARIABLE, GetProp() would
 *   succeed but the two listboxes are not scrollable. Luckily, GetParent() now
 *   works. The following macros would hence reflect those facts. 
 *   Hung.
