Modified Files:
	pcb/src: dev_rs274x.c print.c

Log Message:
Changed print.c and dev_rs274x.c in order to provide negative image ground
planes for gerber output when possible. Some fab vendors can't handle or
charge extra for composite ground planes which is the motivation for this.
Negative image planes are made when (1) There are no lines, arcs, text,
or pads on a layer and (2) There is exactly 1 polygon on the layer and
(3) All vias/holes/pins pierce the polygon. The polygon is then assumed
to consume all of the area and only the thermal reliefs and pin/via
clearances are needed. haceaton 11/19/03
