I'm not sure what the default behavior of subwindows is supposed to be,
but you could just add an ortho2 to your redr to get what you want:

 
 redr(){
 	winset(child);
 	reshapeviewport();

	ortho2(0.0, 200.0, 0.0, 200.0);		/* like this */

 	color(WHITE);
 	clear();
 	color(RED);
 	move2(0,0);
 	draw2(199,199);
 	move2(0,199);
 	draw2(199,0);
 }
