In BBB 0.81, the slide number was base 0, while the shape page number was
base 1. We already have a conditional for checking 0.9+; use that to
add a workaround for old BBB recordings.
The previous code assumed that if a shape event's timestamp was during the
time when a particular slide was visible, then the shape belonged to that
slide. This isn't always true with the text shapes, since a final close
event can be sent after the slide has switched.
For a more future-proof matching, use the presentation name and page number
fields on the shape events when available to match them with the appropriate
slide image.
gnuplot's auto-margins don't work well on this graph, so manually specify
the top/bottom (actually left/right - the graph is rotated 90°) to make
the bars fit better, particularly when using wide aspect ratio slides.
The code was previously dividing by the total number of votes rather than
the max number of votes, which meant it was underestimating the width of
the bars. In some cases, this meant that the label for number of votes would
overlap the percentages.

The code was previously passing the message string provided by the user
directly to jQuery - which works okish if the first character is '<' since
it'll parse it as HTML, but the chat messages don't. As a result, it was
sometimes being parsed as a selector, failing, and raising an exception.
The fix is to put the chat message into a DOM node (have the browser parse
the HTML) before doing the jQuery operation to modify the link targets.
Fixes#3670
Chrome frame has been discontinued for quite a while. The playback code actually
does work in IE if you install an extra codec pack or switch the video format used.
Due to the extra delays added by setting up the closed captions, it happens more
often that the writing.js code will attempt to initialize popcorn on the video
element before the video element actually exists on the page.
(This was always a problem, it's just worse now)
Add a synchronization point which will delay the popcorn initialization until the
video element is ready.
- Getting slide dimensions to properly set the panzoom event when deskshare stops.
- Sometimes there's a panzoom event with the deskshare image dimension at time=stop_timestamp+0.1. We remove it.
- Little refactoring
- Properly inserting deskshare panzoom events. We insert a panzoom event with the deskshare video dimensions and the deskshare start timestamp. Immediately, we insert another panzoom event with the previous slide dimensions and the deskshare stop timestamp, deleting any other panzoom event inside this interval of time.
- Handling when deskshare events occur in timestamp = 0.0
- For now, we are limiting the max dimensions to 1280x720
