f.pixmap='on'; //set the pixmap mode
a=gca();
a.data_bounds=[0 0; 10 10];
//construct two rectangles
xrects([0;10;1;1],5);
r1=gce();
r1=r1.children;
xrects([0;1;1;1],13);
r2=gce();
r2=r2.children;
//animation loop
for k=1:1000
  //draw the rectangles in the pixmap buffer
  move(r1,[0.01,-0.01]);
  move(r2,[0.01,0.01])
