[python-win32] LP_WNDCLASS vs pointer to WNDCLASS

[Henry Baxter]

I also tried using 'pointer' instead of byref, just to see if I could learn
anything. The error is now:

ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: expected
LP_WND
CLASS instance instead of LP_WNDCLASS

Now I'm just more confused...
