This patch adds a CMake option "WITH_CYCLES_DEBUG" which builds cycles with a feature that allows debugging/selecting the direct-light sampling strategy. The same option may later be used to add other debugging features that could affect performance in release builds. The three options are: * Forward path tracing (e.g., via BSDF or phase function) * Next-event estimation * Multiple importance sampling combination of the previous two methods Such a feature is useful for debugging light different sampling, evaluation, and pdf methods (e.g., for light sources and BSDFs).
