Light scattering

Recent changes:

• GCC 4 build.
• Full-scene per-pixel light scattering.
• Scaler manipulator.
• Support of compression into DXT3 format.
• Set of UnigineScript defines by means of API and command line.
• Detection of CPU features via __cpuid and __rdtsc intrinsics under MS Windows.
• JointWheel usage example.
• New PlayerPersecutor object (3rd person look).
• New PlayerActor object (1st person look).

After a set of experiments we have found out that non-uniform scaling of objects produces way too much problems, so this feature wouldn't be provided. Moreover objects scaling noticeably reduces performance so we recommend to use pre-scaled objects.

We are also intensively continuing works on reference manual, now we have a semi-automatic system for documenting our huge UnigineScript library, which contains more than 2000 functions for the moment.
