Players refactoring, render speedup

Recent changes:

• Various render performance optimizations.
• Improved rasterizing occluders.
• Decals from particles.
• ObjectMeshDynamic can be created from a mesh file.
• New type of occluders: WorldOccluderMesh, which can have arbitrary geometry.
• Added WorldTransform, WorldTransformBone and WorldTransformExpression node types for transformation of nodes by a spline, an animation and an expression.
• Added set of functions for easy manipulations with node transformations.
• Binary format of spline files.
• Callbacks for physics, triggers and GUI are moved to the appropriate classes.
• Inheritance of parent object's animation in skinned meshes (useful for attaching clothes to a character body).
• Added field for arbitrary user data in each node.
• Added reflection masks for lights.
• Updated spline exporter for 3dsMax.
• System profiler now accumulates values from counters with the same name.
• Optimization of shadow rendering for LightWorld.
• Fixed screenshot grabbing under Direct3D9.
• Heavily refactored players, now they are full-featured world nodes.
• NodeRef caching on load, it leads to faster world loading.
• Additional sorting of equidistant from the camera transparent surfaces by blend function.
• Improved camera for high-level Character system.
• New high-level controls system in UnigineScript (see data/scripts/input).
• Updated reference manual, added "Programming / High-Level Scripts / Character System" article.

Here is an animation tree scheme for new character sample, which is included in the SDK:

PS: We have updatedUnigine development roadmap for this year, now you can see status of scheduled features.
