PATCH: D3D8 resolution changing

[Alex Pasadyn <ajp@mail.utexas.edu>]

Greetings all,
This is a small patch to let D3D8 applications change the resolution. 
If my previous patch is applied, then it works for Wine-desktop-mode as 
well by resizing the desktop window.

The key here was the reordering of those two header lines at the top of 
this file.  Without that, ChangeDisplaySettings got implicitly defined 
which led to a crash.

ChangeLog:
- Enable resolution changes for D3D8 applications
