LBuffer: render second pass into fullview quad (2 triangles) instead of light geomtry. optim ?? (small geometry fill generate a full screen stencil test)
regorg of debug files
Helpers to create light geometry
(some bugs) but add support to directionnal lights
- refactor the way to add/remove lights
- add display of light geometries (for debug)
fail to display stencil (may require some extension), store for memory
