// Detail Texture as defined in Creator v2.5.1 got lot's of parameters that I don't know 
// how they work, so I have implemented only the things I need, and if someone needs 
// something else it's posible to use other parameters using the new flt::AttrData class
// Now the implemented parameters are:
//        - txDetail_m, txDetail_n : Control how new texcoord will be generated.
//        - modulateDetail         : If set to true, be use scale_rgb and scale_alpha values from 
//                                 osg::TexEnvCombine to make a lighted image.
//
// I implement detail texture as a new TexEnvCombine attribute in texture unit 1
// that is added to the stateset of the geometry.
//
// flt::AttrData class is used to store Texture Attribute Data as defined in Creator
// so we can pass this info to others loader object an use it where needed.
