Advance Lightmapping Module

This represents a customized Grome editing project licensed to various professional companies as part of under-contract customization work.

Fast generation of lightmapping for very large scenes.	Generation of lightmap for both terrain and arbitrary mesh objects
Support for transparent surfaces. Correctly computations of light passing through multiple semi-transparent surfaces. Advance lightmapping to simulate global illumination using ray tracing and ambient occlusion.
Support for multiple lightmaps per each scene entity. Various methods to render and combine lightmaps. Support for unlimited number of light sources. Omni and directional lights with multiple custom parameters. Easy to use gizmo manipulators to place light sources, change lights radius and directions.
