** This function is used to select a primitive.  The given
** location is used to select the target primitive.
** The selection searches a primitive starting from
** the front to the back of the list of primitives.
** It also rebuilds the display list of the entire model so 
** that the selected primitive will appear highlighted.
** This function may also be used to unselect all the primitives,
** in case no primitive is selected at the given point location.
**
**  @param x       - x coord. of point on target primitive    (in)
**  @param y       - y coord. of point on target primitive    (in)

**  @return
**  It returns a true (1) status if a primitive is selected.
**  Otherwise, it returns a false (0) status.
