Public API and Backward Incompatible Change

1. Adding Ellipse annotation.

   // minimal set of parameters
   AnnotationInfo ellipse= new AnnotationInfo()
   {   
       Box = new Rectangle(100, 100.0, 50, 50),
       Type = AnnotationType.Ellipse;
   };
   

2. GetThumbnail method returns JPEG image stream.
   Assume we are getting pages from document:

   List<PageImage> pages = annotationHandler.GetPages(document);
   
   //Then if we want get thumbnail we call GetThumbnail() method of PageImage item:
   foreach (PageImage pageImage in result)
   { 
       Stream stream = pageImage.GetThumbnail(); // do something with stream 
   }
   
   
   // Default image size was 300x180. If need specified image size, you can pass method parameters:
   // image thumbnails 100x100
   foreach (PageImage pageImage in result)
   { 
      Stream stream = pageImage.GetThumbnail(100, 100); 
      // do something with stream 
   }
   

3. Added ability to set text watermarks angle.
   The same as adding Watermark annotation, but you should additionally set Watermark rotation angle by setting AnnotationInfo.Angle property (in degrees)

   AnnotationInfo annotation = new AnnotationInfo
   {
       Type = AnnotationType.Watermark,
       Angle = 45,                
       // another properties
   };
