Inherit NCollection_Buffer from Standard_Transient, do not use incomplete NCollection_Handle. OpenGl_Context, add methods ActiveProgram(),BindProgram() to manage currently active GLSL program. Add method ::ToUseVbo(). OpenGl_ShaderProgram, setup locations of pre-defined vertex attributes occVertex, occNormal, occTexCoord, occColor before linkage. Remove methods OpenGl_ShaderProgram::Bind(), ::BindWithVariables() and ::Unbind() - OpenGl_Context::BindProgram() should be used instead. Introduce class OpenGl_VertexBufferCompat, which emulates VBO behavior on systems without VBO (compatibility with broken OpenGL drivers on Windows). OpenGl_PrimitiveArray - use OpenGl_VertexBufferCompat when VBO is unavailable, remove duplicated code. Use OpenGl_VertexBuffer::HasNormalAttribute() method to activate lighting. OpenGl_Text - use OpenGl_VertexBufferCompat, eliminate duplicated code. Changes in OpenGl_VertexBuffer, drop methods BindFixed()/UnbindFixed(). Superseded by new methods BindAllAttributes()/UnbindAllAttributes() which handle active GLSL program, when it is set.
