70f89a8bce Shadow: Use 4 cascades. 
Now that we use GS and textures array it's easier to add a cascade.
4 is still not optimal but I'd like to avoid cascade count inflation as
much as possible ; 4 x 1024x1024 has the bandwidth requirement of the
single 2048x2048 shadowmaps we previously had.

934d1f10b8 Shadow: Use Geometry Shader for better perfs. 
The 3 cascades are now rendered in a single pass, using 2D array texture and
a GS to do the dispatch ("layered rendering").
It's possible to use instancing instead but it requires the AMD_vertex_shader_layer
extension which is oddly part of opengl 4.2.

f0ef8e9913 Shadow: reenable shadows 
It's just plain basic shadowmaps, a lot of tweak is still necessary but
it gives a way to see how light values are affected in some places.
(cave in chocolate for instance)
