These patches are by Vikram Visweswariah <vikram@isi.edu>
to disable animation features which break some uses of the move
command.  They apply to xgraph 12.0.

A sample input that crashes xgraph_anim:

	TitleText: reno1
	Device: Postscrip
	BoundBox: true
	Ticks: true
	Markers: true
	XUnitText: time
	YUnitText: packets
	
	"packets
	move 1.006 0
	draw 1.006 0
	move 1.22744 1
	draw 1.22744 1

for a longer input run "ns test-script.tcl reno1" and then "bin/raw2xg -q <out.tr >out.xg".
