Graphic3d_CLight is now defined as a class inheriting Standard_Transient, so that it's fields now should be accessed through methods. Graphic3d_CLight::IsEnabled() - new property allowing to disable light source everywhere. Confusing alias OpenGl_Light has been removed. Graphic3d_CLight::SetAttenuation() - the upper limit 1.0 of attenuation factors has been removed since it contradicts to OpenGL specs and does not make sense. Graphic3d_ZLayerSettings::Lights() - light sources list is now property of ZLayer. When defined, it overrides light sources defined for View/Viewer. New class Graphic3d_LightSet has been defined to define a set of light sources. V3d_Light - removed obsolete interface for debug drawing lights sources. V3d_Light is now an alias to Graphic3d_CLight. V3d_TypeOfLight is now defined as a typedef to Graphic3d_TypeOfLightSource.
