Fixed rendering artifact in shadow maps, in Irrlicht 3d view. Previously, fast traveling objects had the postprocessed pixelshading effect displaced respect to the real shape, giving a 'double shape' effect. Fixed.
Support for shadowmapped lights that do not provide the 'border' clamping, so one can create a light whose lightmap is small (for better shadowmap resolution) and still it illuminates a larger portion of the scene. Ex. useful for chasing a car if you care more about the car shadows than the rest of the shadows in the scene.
The demo_emitter.cpp was too advanced to be considered as an introduction to the particle factory features, so it has been renamed demo_emit_processor.cpp and now a newer demo_emitter.cpp will be prepared.
