Lights defintion clean up: - remove duplicated enumeration TLightType (equals to Visual3d_TypeOfLightSource) - remove unused fields from Graphic3d_CLight - OpenGl_Light, reuse Graphic3d_CLight definition Phong GLSL program: - move out cumulative ambient light intencity from limited list of lights - compatibility issues, replace array of structures (light sources, materials, clipping planes) with arrays of primitive types New Draw Harness command vlight to alter light sources definition. OpenGl_ShaderProgram::Initialize() - add missing Linker log
