  the interface but it is more correct way (Microsoft even have a
  resource type of volume).
- Moved usage, format, allocatedMemory and size onto the resource
  class structure.
- Refactored Preload for classes that inherit BaseTexture, preload now
  binds the texture instead of bind texture calling preload, bindTexture
  allocated a glTexture if there isn't one.
- Added two new class static members BaseTexture_CleanUp and
  Resource_CleanUp that should be called by classes that implement
  BaseTexture or Resource.

Move ppVoulme to d3d9voloumeimpl structure.
Some minor stylistic changes (making everything the same).

- store the result of the Interlocked functions and use only this.

- Only prototype the interfaces which are subclassed (I overdid it
  last time!).
- Implement Get/Set Texture and GetBackBuffer, plus device's
  GetDisplayMode / GetDeviceCaps.
- Make some of the d3d9 skeleton code issue fixme's to highlight code
  which hasn't been migrated yet.
- Correct the d3d9 headers for D3DSURFACE_DESC which caused stack
  corruption in demos.

- Add prototypes for the COM interfaces.
- Fix some incorrect types from the last patch.

- Reduce the header includes in all the d3d9 interface to one common
  set in the private header.
