We just added setProps() to Tile, Wrapper, LabelLetters, LabelWords, LabelOnPath, LabelOnArc. And a general CODE function setProps(). Thanks @pettis and @josephd for the thoughts on this.
new LabelLetters("We can now set properties on items")
.pos(0,50,CENTER)
.setProps({color:series(pink,blue)});
new LabelWords({color:yellow})
.sca(1.5)
.center()
.mov(0,-50)
.setProps({
rotation:{min:10,max:20,negative:true},
font:["verdana", "courier"]
});
new Tile().sca(.5).pos(0,50,CENTER,BOTTOM).setProps({color:[red,orange,blue]});
