It was previously trying to get the presentation name from the wrong variable,
which resulted in a nil value (which was treated as a blank string in
filenames). This caused the poll images to not be inside the presentation
subdirectories, and the poll image references in the svg contained a `//`
path, which would break the recording if it was uploaded to e.g. AWS S3.

This fixes font scaling in the presentation area, since that relied on
the <p> element inheriting the font size from the svg <g> that it was
inside of.

This was broken with the switch to the Foundation stylesheet base, which
set a fixed font size on the <p> element.

In some cases, we get DRAW_END events for pencil shapes from the
html5 client that have no dataPoints. The only thing we can really
do here is detect the issue and ignore the shape.

In some cases, this may result in the shape's intermediate drawing
updates being shown, but it'll disappear when the end event happens.

The checks for 0 numerator or denominator were failing due to
type mismatch
