Including system OpenGL headers has been moved from OpenGl_GlFunctions.hxx to OpenGl_GlNative.hxx. Added OpenGl_GlTypes.hxx providing basic OpenGL 1.1 types. Wrappers of system OpenGL 1.1 / OpenGL ES 2.0 functions have been moved to OpenGl_GlFunctions.cxx. Avoided usage of global OpenGL functions in OpenGl package outside of OpenGl_GlFunctions.cxx.
