Open the Graphic Signature tool using a link annotation

A PDF link annotation can execute arbitrary JavaScript code. This sample loads a PDF containing a link annotation with JavaScript code which, when clicked in DsPdfViewer, calls a DsPdfViewer-specific method showSignTool() that opens the Graphic Signature tool.
