[Image-SIG] Using PIL to merge postscript generated text and png files

[Laura & Edward Cannon]

As far as I know, line wrapping in PIL has to be done automatically.
You need to use the font.getsize(text) method in ImageFont it returns
a (width, height) tuple for the given text. A little work will allow
you to write a function to split the lines at the appropriate places
(I would split the text into words with the .split() string method)
and then you can draw each line individually.
