widget: Changing the scale does no longer require a redraw

It doesn't require one generally anyway, because only the root can
change scale and when that happens the root will queue a redraw.

But even if the root doesn't queue a redraw, render nodes (the only
thing discarded by queue_draw()) are scale-independant.
