If Kris' function is called lots of times, issuing an "import pygame"
in it will consume unnecessary cpu-power. This is because as soon as
soon as the function exits, the pygame-module will be unloaded.
Imported modules within functions will not be visible outside it,
because of the scope rules in Python.
