# Automatic Text Wrap (Sky00Valentines Updated Version)
# To the best of my knowledge it is created by coolmariners98 (Atoria)
# To my knowledge they also did not restrict use of this, so from
# May 10, 2010 I will begin using it in conjuction with many scripts I
# Write. Just so I have the quote from the  header from where I go it from.
#
#
#  "Please do not copy and distribute claiming to have created this.
#  I would like full credit, even though this script is kind of crappy."
# --------------------------------------------------------------------------
# However I Sky00Valentine created all methods besides draw_wrap_text
# with or without reference.
#
# also note that on boards I may say my version of Atoria's Auto Text
# Wrap or SAATW.(Sky's Atoria's Auto Text Wrap) Because I have to let people
# who use my script know what I am talking about as I use this a good bit.
# I EDITED AN ALREADY EXISTING SCRIPT AND THE RESULT IS THIS.
