// Parameters:
//  pMsgHdr: The message header
//  pWordWrap: Boolean - Whether or not to word-wrap the message to fit into the
//             display area.  This is optional and defaults to true.  This should
//             be true for normal use; the only time this should be false is when
//             saving the message to a file.
//  pDetermineAttachments: Boolean - Whether or not to parse the message text to
//                         get attachments from it.  This is optional and defaults
//                         to true.  If false, then the message text will be left

//                         in the message text (for multi-part MIME messages).
//  pGetB64Data: Boolean - Whether or not to get the Base64-encoded data for
//               base64-encoded attachments (i.e., in multi-part MIME emails).
//               This is optional and defaults to true.  This is only used when
//               pDetermineAttachments is true.
//  pMsgBody: Optional - A string containing the message body.  If this is not included
//            or is not a string, then this method will retrieve the message body.
//  pMsgHasANSICodes: Optional boolean - If the caller already knows whether the
//                    message text has ANSI codes, the caller can pass this parameter.

// Return value: An object with the following properties:
//               msgText: The unaltered message text

//               topMsgLineIdxForLastPage: The top message line index for the last page
//               msgFractionShown: The fraction of the message shown

//               solidBlockStartRow: The starting row on the screen for the scrollbar blocks
//               attachments: An array of the attached filenames (as strings)
//               displayFrame: A Frame object for displaying the message with
//                             a scrollable interface.  Used when the message
//                             contains ANSI, for instance.  If this object is
