From 35512aa7e4acc3ceb9c6aef5d61eebfb4ae802af Mon Sep 17 00:00:00 2001 From: jaepark Date: Mon, 29 Aug 2016 17:15:08 -0700 Subject: Display content of the annotation when mouse hover. Each annotation has its contents, and users should be able to see the contents. In this patch, PDFium creates a Popup annotation for each annotation and stores the author and the content. When a user mouse hover on the annotation, PDFium draws the corresponding Popup annotation and displays the content. Also, roll DEPS for testing/corpus to 5867fa6.
