Detailed Description

Global default gray color material for meshes that don't define their own.

Because the default material depends a default shader program (SLGLDefaultProgPerVrtBlinn or SLGLDefaultProgPerVrtBlinnTm) that itself depends on the scene configuration (e.g. the num. of lights) ist MUST be deleted at scene destruction.
