// Normally a the Right Margin is handled by the RichTextBox it defaults to a value of 0.

// If the RightMargin is equal to the width of the RichTextBox the word-wrap occurs just beyond
// the visible extent (right edge) of the RichTextBox when it is in view mode. In edit mode it
// wraps within the visible extent. An example of this is Step 24 of ES02 in HLP EOPs.

// If the RightMargin is greater than the width of the RichTextBox, the word-wrap occurs beyond
// the visible extent of the RichTextBox for both view and edit modes.
