GtkCalendar: Style classes are not documented
Submitted by Daniel Boles
A bunch of style classes that get piled onto the single calendar node are queried to style various bits of the Cairo monstrosity:
.day-name .day-number .week-number .header (containing year, month, and buttons) .highlight (background of day names and week numbers) .button (arrows)
These are not documented. The setup is not ideal, and only a subset of properties are actually honoured, but it might be a good idea to mention them anyway?
