Historically for the cairo device drivers, the graphical antialiasing looked bad for examples 08, 16, 20, and 30.  Therefore, we turned off graphics AA for these examples for our website.  However, since Werner's filled_polygon change to the cairo driver, graphics AA looks better (or at least is no worse for the example 30 case) then if graphics AA is turned off. Therefore, take the default (graphics AA turned on) for these examples just like all other examples.
