/*
* How rendering works:
* The page is fit into the browser window with fixed dimensions (defined below) and then html2canvas
* rebuilds the DOM to capture an initial snapshot of it. However, since the full sized screenshot
* is too large to be cached (you can attempt this but will likely encounter the cache returning
* failed status as the key is too large) the initial snapshot is then used as a background for a
* div that is resized along with the said background. After resizing, a second snapshot is taken of
* the now resized previous snapshot and this small version is sent to cache through $.post().
* Javascript is user-agnostic, all security checks are done on PHP side, the interface isn't
* available and no keys are cached if the required privileges aren't present. Check your privilege.
