Int 62 Fn 007A  u - Fgdriver V3.03 - "fg_polyline" - Draw An Unfilled Pol  [V]

   AX = 007Ah
   CX = number of vertices in polygon
   ES:BX -> vertex array (see below)

Notes: For FGDRIVER v1.10, this function was "FG_MOUSEINI" (see AX=0061h);
      "FG_POLYLINE" did not exist yet
   This function is equivalent to "FG_POLYGON", but uses only a single
     array to define the vertices
   This call is ignored in text modes
