Bruno BELANYI 8e09f45f69 library: render: move helpers to utils module
Those helper functions are used by `Scene` to render the scene, but
they have no use being in the same file. Instead make it a crate-public
module of `render`.

Bruno BELANYI c0c332e3fa examples: triangles: fix ball diffraction index
The ball was intended to be a glass ball, so an index of 1.5

Bruno BELANYI 70c0e0cdf3 library: render: scene: handle refraction cleanly
The refraction information was incorrect in the previous implementation.
We never updated the medium information when going out of a transparent
material. It is now handled using a small structure holding both the old
index, and new_index.

We can now handle any number of successive medium changes, with the
associated change of indices correctly.

This implementation assumes that any ray going into an object is going
to come out in the same medium that it was originally travelling in
before entering said object. This is an acceptable approximation to me.

Bruno BELANYI b29e6d1613 library: render: scene: fix reflection handling
The reflection will be calculated even if it ends up not contributing to
the final color of an object. This allows for a more systematic use of
coefficients without applying them twice, like it was done for the
refraction transparency handling...

Bruno BELANYI 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.

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 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.

Instead of having a method per property, compute them all at once and
use them throughout the rendering pipeline.
