// The next thing is a bit tricky.  DefineEngineMethod allows to make the 'object' (=this) argument to the function
// implicit which presents quite an obstacle for the macro internals as the engine export system requires the
// name of a DLL symbol that represents an extern "C" function with an explicit first object pointer argument.
//
// Even if we ignored the fact that we don't have a guarantee how the various C++ compilers implement implicit 'this' arguments,
// we could still not just use a C++ method for this as then we would have to get past the C++ compiler's mangling to
// get to the function symbol name (let alone the fact that typing this method correctly would be tricky).
//
// So, the trick employed here is to package all but the implicit 'this' argument in a structure and then define an
// extern "C" function that takes the object pointer as a first argument and the struct type as the second argument.
// This will result in a function with an identical stack call frame layout to the function we want.
//
// Unfortunately, that still requires that function to chain on to the real user-defined function.  To do this
// cleanly and portably, _EngineMethodTrampoline is used to unpack and jump the call from extern "C" into C++ space.
// In optimized builds, the compiler should be smart enough to pretty much optimize all our trickery here away.
