/// <p>ApplyParagraphStyle begins by getting the paragraph properties from the
/// selection. If paragraph properties cannot be retrieved through a selection,
/// ApplyParagraphStyle returns false. If no text properties are retrieved in vttp,
/// ApplyParagraphStyle returns true since there is nothing to do.</p>
/// <p>Next, immediate changes are made to paragraph properties retrieved from the
/// selection, and the variable vttp is updated.</p>
/// <p>If ApplyParagraphStyle has not returned as described above, it narrows the range
/// of TsTextProps to those that are not <c>null</c>. Then, it saves the view selection
/// level information by calling AllTextSelInfo on the selection. To "fake" a property
/// change, PropChanged is called on the SilDataAccess pointer. Finally, the selection
/// is restored by a call to MakeTextSelection on the RootBox pointer.</p>
