Comment 8 for bug 1069172

Should be fixed in lp:inkscape r11981. In Gtk+ 2 builds, we use a hack to account for a mysterious 2-px offset. In Gtk+ 3 this doesn't appear to be necessary. We should still try to figure out why it's needed for Gtk+ 2 builds though.

I've also merged in a lot of the rendering code from GIMP. Please let me know if the weird black rectangles are showing with certain themes... we can handle this as a separate bug.
