/*! class RGTextMessageRequester
 *
 *  Request displaying a text message, and getting a button result.
 *  This class is different than RGMessageRequester since it uses a
 *  TGTextView, to display long texts.
 *
 *  The request may contain two additionnal buttons (that do not close the
 *  request):
 *  - a "save" button to write to file (option rgTextReqSaveButton)
 *  - a "print" button (option rgTextReqPrintButton)
