Post processing

Is there any ability to post-process rendering. So after *->drawAll()s I can get pointer to a buffer that contains RGBA of all pixels that will be on the screen next frame ?
Is it possible something like that?

If you need to do things like blurring, heat vision or some other fullscreen post processing thing you should do something like this:
1)Render all your scene to a texture.
2)Do the post processing.
3)Render texture to screen.
Also, you should probably check some of the post processing examples in the Code Snippets section.
