Evas filters: Implement bump maps

These bump maps implement two light effects at once:
- 3D Shadows
- Specular lights

The specular light is activated by a flag.
Another flag enables compensation for darkening/whitening of
horizontal surfaces.

NOTE: This implementation is VERY SLOW.
It uses double values and divisions all over the place.
It might be possible to optimize by computing two LUTs before
running the algorithm.
