40c2ae1bc9 library: render: scene: more like-like refractions 
The refractions are now implemented using the Fresnel equations to take
into account the amount of light that is reflected off of transparent
surfaces.

For example, this leads to a small amount of discoloring at the edges of
the ball in the example scene. Indeed, this ball has a refractive index
higher than diamond (!), so its edges reflect light much more than when
looking at it dead-center.

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.

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.

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.

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.

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.

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

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.
