I'm not sure they are the same, since I can still make it work by
implementing a pseudo ID2D1HwndRenderTarget_GetSize with assembly code
which is exactly the same with the exception of rax and rdx swapped. And by
working, I mean not crashing, I still need the workaround for the wrong
data which you pointed, and that I implement directly into code.
