Performance does not scale well with very large slide shows #2530

When presenting slide shows with hundreds of slides, the slide transitions are very slow: of the order of several seconds on a modern laptop.

The issue occurs on both chrome and Firefox.

Performance profiling in Firefox (see screenshot below) seems to indicate updateSlidesVisibility() as one potential bottleneck.
