This doesn't look FBO-related; it looks like a difference in rendering. FBO
errors tend to have nothing work, not have the rendering look incorrect.

I have a simple FBO class implemented. It is used in several of my projects
(e.g. my GLSL game of life
implementation<http://geometrian.com/programming/projects/index.php?project=Game%20of%20Life>).
You can use it as a reference.

As before though, it looks like some broken matrices or shading--not a FBO
issue.
