The OBJ loader is incomplete, the MTL part of the loader must be added

For now, only one global scene is supported. The scene components can be added and removed, but we might imagine different scenes with different opengl features, e.g. immediate vs. deferred lightnin or other variations with global impact.

Add drawing helpers:

• object helpers : vertices, triangles, normals, (textcoords ?)
• world helpers: origin and X/Y/Z unit vectors, grids for X/Y/Z planes
• camera helpers : position, orientation (front/right/up vectors)

For now the shader code is written as standalone files. A more dynamic approach should be used, for example to allow for a variable number of lights.

Support for model as found in IQM or GLTf3

Shadow mapping is not applied correctly since shader code remodularization.

The light system is buggy, and does not support all features of common light properties (cf. MTL material description and issue #16

Add mesh generation algorithms:

• basic meshes : planes, cuboids, cones, cylinders, tores, spheres, polyhedrons ...
• curved surfaces
• more advanced meshes (?)

There is a preliminary support for so-called drawing strategies, i.e. different ways of drawing meshes. The system should be put into practice:

1. allowing various strategies : default (using material), gouraud/phong/..., wireframe, and helpers (e.g. normals, ...)
2. allowing to compose drawing strategies

The shader code is dependent on the (maximum) number of lights (points, spots), but for now it is a constant in the shader code.
A simpler improvement would be to allow these limits to be fixed at the time of constructing the main shader programs.
Also, unusued light slots should not lead to computations.
More challenging would be to adapt the shader code dynamically when changing the number of lights. This is related to the support of scene install/uninstall
