Subject: [PATCH] Fixed QueryInterface on same interface

Because multiple DirectDraw interface versions may share the same
method implementations, CompatVtable may dispatch calls to an earlier
interface where that method implementation was already hooked.

Therefore a call to QueryInterface is needed even if the method
thinks the result will be the same interface type; a simple
AddRef may not have the same effect.
