+%
+% \paragraph{Regarding the gap issue:}
+% The pixels are output touching each other with no real gap, however some
+% \textsc{pdf} viewers and tools will display such a gap. To make things even
+% worse, the effect depends on the viewers current magnification.
+% \pxpicname\ has the |gap-hack| option to provide some crude hack that might
+% fix the issue, at the cost that the pixels are smaller than they were
+% specified to be, except for the pixels at the right and bottom border. Also
+% pixels next to skipped pixels have a different size (skipped pixels don't
+% cover pixels to their left or top as they are transparent). You'll want to
+% find a good trade-off value if you want to use |gap-hack|, that mitigates the
+% effect but isn't too big (to make the errors less obvious). You can play with
+% the value and decide for yourself what's the lesser evil. Or you do like me,
+% don't use |gap-hack| and blame the viewers.
