Open FPDFDest_GetView API.
FPDFDest_GetView returns the view fit type and the parameters of the view for a given destination. This is useful to have more precise internal links and bookmarks that are able to manipulate the viewport position and zoom level to focus on the part of the PDF that it links to.
