Printing to PDF doesn't work with AGG, IIRC.

which are at the bottom of the stack anyway) so you can see through the
layers to see the layers underneath the current layer. The problem is IE
6 (and earlier) does not display 24-bit transparent PNGs correctly. IE 7
and just about any other browser should work fine.

however if you have more than a few colors in the map, you will loose
some of the advantage of AGG because it won't have enough colors (of the
256) left to do the dithering.
