Remove automatic zbuffer write enable in transparent d3d materials. To be done by the user, just as the OpenGL materials already do.

 Changes in version 1.4 (... 2007)
 
+ - D3D transparent materials do not disable zbuffer writing automatically anymore. This has to be done by the user to keep those settings configurable.
+
+ - OpenGL texture now also require a regenerateMipmapLevels() after unlocking. This is the same as for d3d devices now.
+
  - Point sprite support in the driver. Point sprites use just one 3d vertex and a size to create a textured billboard on the GPU. This can provide fast particle systems, especially in combination with shaders. The proper particle extension will follow later on as it needs some more refactoring.
 
  - OpenGL 2D drawing accuracy fix by tuXXX
