   Print screen
  Hihi. i am trying to print screen of my application so as to document it. But somehow it does not copy the whole screen. i feel that it is due to the rendering sequence. So is there a way to print the whole screen?   
  Im not sure if in windows print screen works with 3d hardware accelerated windows, plus theres always the chance that it might work on your OS version but not other pplsto see what the current pixels of the opengl windowuse glReadPixels + save the result as an image
