surface.c/*texture.c (with add of lockable, locked and Dirty flags)
- add of dirtyRect/dirtyBox for better dirtification management (not
used yet, but huge optimisation can be possible now)
- fix some debug traces (well it's better to use debug_d3dpool)
- fix some stupid regression on point parameters (forgot to check
extension on fillcaps)
- minor indentation and traces fixes
- fix locking/unlocking/dirty behavior (dirtify on lock) +
optimisations (only copy when dirty)
- fix IDirect3DDevice8::Clear behavior (problem seen after a
locking/unlocking code error)
- begin to fix volume and cube textures management
- minor indentation changes
- fix SELECTARG2 behavior (with help from Lionel Ulmer)
- surface locking/unlocking (only rendering and textures surfaces
supported now)
- beginning of Target/Front surface support
- try to get D3DTOP_SELECTARG_* working
- implemented D3DTOP_SUBTRACT: currently only if OpenGL1.3 is used, we
have to use GL_SUBTRACT_ARB for other versions
- beginning of shaders support (Vertex and Pixel Shaders 1.1 on
DirectX8)
- beginning of D3DX8 support the D3D8 utility API (very basic, only
the core header)
