Function ConvertEffectConstant

trinity/Shader/Tr2Effect.cpp:125–201

-------------------------------------------------------------------------------------- Description: Look at the constant and build an ITriEffectParameter out of it Arguments: constant - constant being analyzed constantValues - blob with the default value for the constant adder - callback function that's in charge of actually adding the newly created parameter --------------------------------------
