	Using `GL_RGBA32F` as the texture storage format instead of packing values into the unit interval.
2019-09-23	Implement basic diffusive lighting in volumetric raytracer	Adrian Kummerlaender
	Approximated surface normals are encoded into the moments texture. These normals are restored when the ray marcher encounters an impermeable cell. Note that normals are shifted to be >= 0 as negative values are not representable using OpenGL textures. If this prototype works out it might be preferable to calculate better surface normals during preprocessing to be stored separately. Compare to 6123c8a.
