We can set custom fonts to look better... vert is doing this.

From DM... different screen sizes have different px height fonts.. he's what he uses

function charheight(rows)
 {
 	switch(rows) {
 		case 27:
 		case 28:
 		case 42:
 		case 43:
 			return 14;
 	}
 	if(rows <= 30)
 		return 16;
 	return 8;
 }
