Viewport

• window and fullscreen 16/32 bit color modes (probably 24, too)
• event polling + event controlled redraw modes
• vertical blank synchronisation (win32)
• a note on object picking: you need to allocate a picking color first (SDL.allocPickingColor()). Now the strategy is:
  • use that picking color to draw a small pixel on the screen before you draw your "pickable" object
  • draw your object
  • grab the pixel at the mouse coordinates from the GL RGB(A) framebuffer (use zglReadColorPixel())
  • if the pixel is not there anymore, also grab the 'z' value from the GL depth buffer (use zglReadDepthPixel()), otherwise the object is not under the current mouse cursor (since it did not overdraw the magic pixel)
