PDFViewer_v100

[hh]

Just updated PDFViewer (uses parts of pdf.js,
see https://github.com/mozilla/pdf.js ).

Use it if you can't/won't rely on the user's PDF-plugin.

Download PDFViewer_v100 from "Sample Stacks" or
http://livecodeshare.runrev.com/stack/916/

Current features:

* Switch to prev/next/any page of the PDF.
* Zoom in/out or fit the PDF to width/height of the widget.
* Rotate the PDF to 0, 90, 180, 270 degrees.
* GRAB mode: Grab the PDF to scroll it left/up/right/down.
* TEXT mode: Select and copy text from the PDF.
* Switch pages also with arrowkeys in both modes.
* History of used files.

You can display both local and remote pdfs. And we do NOT need
a local server or a temporary file system. The full viewerJS of
the library can NOT do this without a server.

The library is included in the stack. Stack size < 500 KBytes.

Tested to work with LC 902 on 64bit of 
MacOs 10.14,  Win7+10, ubuntu1604 
Works also with LC 8.1.10 on Mac/Win, but NOT on linux.
