use 'ptr'.

not multiple sets of polygons.

piping the PostScript through something before it gets sent to the
printer (like we can already do for non-cups systems).

Fixed a memory leak.

- 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

- added handling for some new texturing ops
- prepare for addition of multi-texturing
- another way to fix the device enumeration for the reference device
- fix compilation with some glext.h files
- fix a bug in one texture conversion function
- added new texture format (but still texturing problems in 3DMark2000)

- added locking for concurrent access to the D3D device
- improved tracing
- added support for most texture combine stages (inspired by the D3D8
  code)
- disable current lock / unlock code pending proper solution

- 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
