Please advise :(. Is it possible to find out, if a handle is a window and return the size?

The handle is a device context, an HDC. It is possible to find out the size of a window, for example using GetWindowRect, but that function wants an HWND, not an HDC.

Otherwise return false.

The return value of GetDeviceSize isn't used (and the default implementation returns false already).
