[LRUG] PDF generation from HTML with complex JS

[Stephen Bartholomew]

Yeah that's certainly what it looks like, but wkhtmltopdf uses webkit as a
headless browser - and you can tell it to wait before producing the html.

Using a browser does seem like the obvious option, but even printing
straight from safari for example doesn't correctly show the map.  Feels
like a screenshot is the only way right now!
