You can access the display's surface (a linear, 8-bit palettized
framebuffer) if you use the SDL target. If you use the OpenGL target, you
could add a call to glReadPixels() to see what's in the framebuffer, which
will slow the engine quite a bit if you do it every frame, but will give
you a considerably higher quality image (if that's important).
