With GN's help, got the presentation code set up with our HCMC theme, using pure SVG for the logo, and coded the first three sections of the presentation (which are fairly straightforward). A Firefox 4 beta came out today, so we downloaded and tested that, and discovered that its JS engine is now on a par with Chrome, so we'll be able to use Firefox even for large presentations using this codebase in the future; version 3.6 was really unable to cope with the Coldesp presentation, so this is a good thing. It's especially so because it turns out that Chrome's SVG support leaves a lot to be desired; it seems to fail to handle the fill-opacity setting in text and tspan elements.
