Feature request: Keep user strokes and supply a score in quiz()

[philipmonday]

Hi, Chanind,
Thanks for your great work.
Please consider the case:
At the beginning, the writer has been set with showOutline: false and showCharacter: false, then user start to quiz. While quiz, I hope the writer can keep user strokes appear all the time until user finish quiz. Then, the writer will show outline of the char and supply a score to tell user how close( or how good ) their own strokes to the standard char strokes. Of couse, the closer the better. I think this is a important way to help user remember all strokes of char without any hints, also help them to write better hanzi.

so, the core request is to keep all user strokes appear instead of vanished at the end of one stroke currently.
Thanks again.
