  1. Don’t try to put the entire post in the title.
  2. Use
 or

tags for code. This is particularly important for Python as it uses whitespace for block structure.
3.

Where does that 480 come from? You would normally use [var]height-1-y[/var] to translate coordinates from top-left-origin (used by most windowing systems and GUI toolkits) to bottom-left-origin (used by OpenGL).
