9  * This class extends javax.swing.text.WrappedPlainView. Its primary
10  * purpose is to change the word wrapping methodology so that the text
11  * of new messages is wrapped on the screen at a character boundary, just
12  * as it will be when it's actually sent. So in other words, this
13  * class makes it so, if you have your mail client set to line wrap at 72
14  * characters, your mail entry window will also wrap at 72 characters, no
15  * matter what the size of your font or your window is.
