Added BindTexture, GetTextureDimensions, UnBindTexture.
Proper GetContainer support for surface.
SetContainer added to surface and volume.
SetInPbufferState added to surface (until gl context management is
implemented).
Minor changes:
- BaseTexture no longer 'holds' a reference to IWineD3DDevice to
prevent circular referencing.
- Better managment of referinging for texture.
- Some TODO's for implementing a context manager.
- Better preload implementation.
- Fix compile warning in device.c Set/GetSamplerState.
- Add QueryInterface support for surface.
- Format X8R8G8B8 added to locking.
- 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.
