according to the docs:

Code:
DLL void showOverlay(   float    x_tl,
   float    y_tl,
   float    u_tl,
   float    v_tl,
   float    x_bl,
   float    y_bl,
   float    u_bl,
   float    v_bl,
   float    x_br,
   float    y_br,
   float    u_br,
   float    v_br,
   float    x_tr,
   float    y_tr,
   float    u_tr,
   float    v_tr,
   float    colR,
   float    colG,
   float    colB,
   float    colA,
   ResHandle    materialRes,
   int    layer   )


the 20th(colA) parameter is alpha. increasing it or decreasing it in your loop (calling alpha++ each time for example) will get you that transition
