Bruno BELANYI 552c0cb966 library: implement refraction 
This necessitated to rework how light properties for a material were
given. A material can have either reflectivity or transparency. This
changes the parsing of materials, using a `LightProperty` structure at
its core.

This is does not implement the true Fresnel equations to take into
account the amount of reflection that an incident goes through when
encountering a transparent object.

Bruno BELANYI e00950c7e5 library: render: scene: fix spatial lighting 
The spatial lighting did not take into account the object's color when
calculating the amount of diffuse and specular light that was emitted.

Bruno BELANYI e11598fc9c library: render: scene: clamp colors before sum 
This was a recurring bug in a previous implementation, clamping the
colors before taking the sum of a series of calculations avoid adding a
negative value to a positive one and getting a result which does not
make sense.

Bruno BELANYI 563a793273 library: refactorize light properties handling 
Instead of having a method per property, compute them all at once and
use them throughout the rendering pipeline.

Bruno BELANYI 3257598913 library: render: scene: use rayon scope parallelism 
The implementation was very easy to write, but is not yet optimal. It
would be better to use `join` to divide into tasks directly on the
stack. And it would be better to iterate over entire blocks of rows
instead of giving a row per-thread: this would lead to better cache-line
behaviour with the fully linear memory accesses.

Bruno BELANYI 67628ec083 library: render: object: add deserialization 
By using `enum_dispatch` and deserializing the enums, you can very
easily represent the `Object` in serialized form.

Bruno BELANYI 05fb6601b2 library: use enum_dispatch on Object related trait 
This allows for easier testing (notable allowing for comparisons),
better performance (thanks to inlining instead of vtable indirection),
and should ease the deserialization of `Material`, `Shape`, and
`Texture` traits. This should allow `Object` to be deserialized easily.
