while we're on the PNG driver, there's a bug in it somewhere which makes
R_polygon_rel and R_polygon_abs draw one pixel too far to the right and
one pixel too far down.
Presumably in src/display/devices/PNGdriver/Polygn_abs.c ?


seen in d.legend, d.histogram, and d.colortable ...

Drawing commands pass the same coordinates regardless of driver..
(ie it isn't different window size used for setting the coordinate?)
