// DESCRIPTION:
//      Tool for dynamic referencing of hardware rendering functions
//
//      Declaration and definition of the HW rendering 
//      functions do have the same name. Originally, the
//      implementation was stored in a separate library.
//      For SDL, we need some function to return the addresses,
//      otherwise we have a conflict with the compiler.
//
