Reflective Shadow Map

Real-time rendering of indirect illumination by using adaptive sampling of the Reflective Shadow Map (RSM). Supports fully dynamic lights and scene geometry and does not require any kind of asset conditioning.

Update v1.1.1 - optimizations to the Reflective Shadow Map:
*the indirect light is now stored in a separate quarter-resolution buffer so as to reduce the number of samples from the RSM
*the quarter-resolution indirect light accumulation buffer is upscaled with an edge-aware bilateral filter and composited to the full-resolution light accumulation buffer using additive color blending
