Discussion on General Design

UI

• New class FL_GL_Window that is parent to ViewGLWindow
• ViewGLWindow owns handle() and draw() method to be implemented
• UI kids (SliceViewUI, VolumeViewUI...) contain instances of ViewGLWindow (m_viewgl)

GL

• ViewGL contains object m_ui for UI update
• ViewGL and kids just for output and code on how to handle input. Observing is taken care off by ViewGLWindow group
