This argument adapter class allows either RECT pointers or references to be passed to a function that is implemented in terms of pointers.
This class and its members cannot be used in applications that execute in the Windows Runtime.
The class defines two constructor overloads: one accepts a RECT& argument and the other accepts an LPRECT argument. The first constructor stores the address of the reference argument in the class's single data member, m_lpRect. The argument to the pointer constructor is stored directly without conversion.
