The epic 0.4.0 merge of the bidirectional branch -- sorry not to do this in smaller batches, but doing so would have been an incredible amount of work. A through description of the changes will be made available on the blog this week.

A batch of changes that have piled up:
...
- Cleaner build system organization (1 SConscript file per directory instead
of a single huge file)
- Robustness improvements to the KD-tree construction code (now does a better
job at handling degenerate triangles)
- Switched to an epsilon-free KD-tree traversal loop using Havran's T_{AB}^rec
algorithm
- Generalization of the KD-tree construction code (now supports plugging in
arbitrary tree construction heuristics)
- Addition of some utility code (LRU cache, adaptive Gauss-Lobatto
quadrature, etc.)
- Generic dense matrix class that supports arbitrary dimensions
- Pixel traversal within image blocks now uses a space-filling curve
ordering
- Added support for several noise functions from PBRT
- Cleanups of various top-level interfaces (Luminaires, Phase functions,
BSDFs, Participating media, etc.)
- Robustness improvements to the participating media code (faster + now
does a better job at dielectric boundaries)
- Added a basic tonemapping utility (can be invoked via mtsutil)

Unfortunately, no history for the existing files could be imported from
the previous SVN repository (it is mixed with as-of-yet unpublished research).
