// CGAL::OGL::Nef3_Converter so we can implement our own draw function
// that does not scale the model. so we define 'class' to 'struct'
// for this header..
//
// theoretically there could be two problems:
// 1.) defining language keyword with the pre processor is illegal afair
// 2.) the compiler could use a different memory layout or name mangling for structs
//
// both does not seam to be the case with todays compilers...
