+As of this commit all "pages" will be 2-sided. Meaning indices { 0, 2, 4, 6, ...}
+are front-facing and { 1, 3, 5, 7, ...} back-facing ones. This happens when page is on right side.
+On left side page is "flipped over" similarly as a page does on a regular book.
+
+Here's an example video from cags12 showing 2-sided page support in landscape mode;
