RFC: ddraw: Fix conversion between D3DVIEWPORT and D3DVIEWPORT2

[Octavian Voicu]

Hi,

Attached is a series of patches to add better tests and fix Wine's
implementation of the conversion between D3DVIEWPORT and D3DVIEWPORT2
structures in IDirect3DViewport / IDirect3DViewport2 / IDirect3DViewport3
implementation.

I'm sending this to to wine-devel because next commit round will be on
Monday, so I hope to get some feedback until then and fix any issues before
sending to wine-patches. I'm also working on
fixing IDirect3DViewport::TransformVertices, which at the very least does
not work if viewport data is set using D3DVIEWPORT2. This will fix bug
http://bugs.winehq.org/show_bug.cgi?id=11819, which is actually caused by
Wine's buggy implementation of TransformVertices and has nothing to do with
the z-buffer locking not begin implemented. I'm working on some tests and a
fix, and will post them here when they are ready.
