Implementing GrpahicsEngine class

[patrick]

this class should become a little primitive GraphicsEngine that manages things like:

• concrete use:
  • setting up all SDL attributes
  • setting up all lights, materials
  • able to reinig SDL if the graphics mode/resolution should ever change during game
  • determines wether the drawable objects should be drawed or not (depends also from mode, like debug mode draws everything)
  • manages to display images, films, menu, console etc.
  • should be able to calculate the computer/graphics speed to set the optimal resolution settings (future)

• requirements:
  • see concrete use

• implementation:
  • class that is loaded at startup in the init section of orxonox.cc
  • class is a singleton
  • class works in different modes: menu-mode, film-mode, image-mode, game-mode (more?)
  • manages light sources, shadows, effects.
  • state of the graphics engine must be displayable (debug function)
