- more cubetextures fixes (now d3d8 sdk cubemap sample work almost
  perfectly)
- add a new debug function "debug_d3dpool" and use it

  surface
- a very simple cliplane fix
- a stupid palettes fix (stupid language)
- begin of anisotropic filter support
- begin of compressed textures support
- a very useful debug functions: IDirect3DSurface8Impl_SaveSnapshot to
