///\brief
///A memory device context. MemoryDC is used internally by various classes,
///including Window, for flicker free drawing.
///
///When performing graphics operations on a Window's DC, changes are drawn
///directly to screen; this leads to flickering. MemoryDC creates an offscreen
///buffer that "accumulates" changes, which are copied to a desination DC
///when all drawing has finished.
///
///MemoryDC is constructed with an HDC and a Rect as parameters, and provides
///an implicit HDC cast operator that returns a handle to the offscreen buffer.
///This means that regular Win32 drawing routines, such as DrawLine, FillRect,
///etc, can transparently use a MemoryDC as if it were a regular HDC.
///
///When a MemoryDC's destructor is called the contents of the offscren buffer
///are automatically copied to to the HDC it was constructed with, resulting
///in flicker-free drawing.
///
///\code
///PAINTSTRUCT paintStruct;
///HDC hdc = ::BeginPaint(this->Handle(), &paintStruct);
///{
/// MemoryDC memDC(hdc, paintStruct.rcPaint);
///
/// //...
/// //draw to memDC as if you were drawing to hdc
/// //...
///
///} // when the MemoryDC destructor is called, the contents will be copied to hdc
///::EndPaint(this->Handle(), &paintStruct);
///\endcode
