# * Version History :
#
# Version 1.0 -------------------------------------------------- (2009-05-22)
# - First release
#
# Version 1.1 -------------------------------------------------- (2009-05-25)
# - The pause image now appears immediately when F12 is pressed.
# - Transitions are cut short rather than restarted when F12 is pressed.
#------------------------------------------------------------------------------

#
# This script changes the functionality of pressing F12 during the game
# from resetting the game to (un)pausing the game. A picture is displayed
# while the game is paused. (Having a picture is optional)
