Graphic3d_TypeOfShaderObject enumeration has been extended by Geometry shader object type. OpenGl_ShaderProgram::Initialize() processes new shader object types when supported by OpenGL version. Declarations.glsl has been fixed so that occFragColor is defined only for Fragment Shader object only (by handling new FRAGMENT_SHADER macros). Improved documentation of Graphic3d_ArrayOfPrimitives class. vshader Draw Harness command has been extended to support definition of Shader Object types other than Vertex and Fragment shader.
