One caveat is that the png antialiasing can only be used with line widths of 1 - if you specify wider lines and have antialiasing turned on, they will always be drawn with a width of 1. >(Same) Some png and pngcairo examples (especially example 3 and example 13) >have large black margins around them.

I think this would be caused by plplot and not the drivers. With respect to margins, the drivers are "dumb" and just plot what plplot tells them. >(Better) There is a bug in -dev png that shows up for the second and >subsequent pages of some plots.

Can you try repeating it with text smoothing turned off and see if it still occurs ? This one looks more like a freeetype issue.
