Subject: Added Zoom control, Window thubnail

Added zoom-in and zoom out capabilities, also re-enabled window thumbnail which I had disabled previously when the thumbnails were not implemented.

Still trying to get the document to display, need to make the right changes, also trying to stop the window from entering presentation view, but that does happen and needs to be fixed.
