I have written (copied ) this program taking example from SMARTSHADER Cel Shade.pss.
should work on all dx9 cards.

gpuPeteOGL2.vp:

!!ARBvp1.0
OPTION ARB_position_invariant;
MOV result.texcoord[ 0 ],vertex.texcoord[ 0 ];
END

gpuPeteOGL2.fp:

!!ARBfp1.0

PARAM One = {1.0, 1.0, 1.0, 0.0};
PARAM OneAndAhalf = {1.5, 1.5, 1.5, 0.0};
PARAM half = {0.5, 0.5, 0.5, 0.0};
PARAM darkIntensity = {0.1, 0.1, 0.1, 0.0};
PARAM brightIntensity = {0.7, 0.7, 0.7, 0.0};
PARAM shrink = {.99, .99, .99, 0};
PARAM r = {1.0, 0.0, 0.0, 0.0};
PARAM g = {0.0, 1.0, 0.0, 0.0};
PARAM b = {0.0, 0.0, 1.0, 0.0};
