What is the D version of `createSizeIntWH`? In C++ it returns a pointer but in D version it returns an instance.

extern(C++){
     cv.Size_!int createSizeInt();
     cv.Size_!int createSizeIntWH(int w, int h);
     void deleteSizeInt(ref cv.Size_!int sz);
}

createSizeIntWH returns a pointer to instance, not an instance. Try:
cv.Size_!int* createSizeIntWH(int w, int h);
