This call works fine under GTK, but results in an "unknown font style"
error on my XP box:
font = wx.Font(8, wx.NORMAL, wx.SWISS, wx.NORMAL)
I've also tried the wx.FONTFAMILY_* versions of the constants. I guess
the default swiss font isn't a TrueType font and doesn't have a size 8
or something? I'm just trying to get a small, sans-serif font. What is
the easiest way to do it that will work under GTK and Windows, if the
users only have the default fonts installed?
