Turtle - rotate head when shape is set to image

[kbialowas]

Feature or enhancement

Proposal:

I found turtle module to be a great way to introduce my kid to programming. I spotted that he is especially enjoying some interactive scripts, that react to keys or clicking. My problem is that currently when head shape is set to an image, it's not getting rotated which is quite a limitation when it comes to achieving some interesting effects while keeping the code simple.

Would you consider adding an option to rotate turtle head shape when it's set to an image to the library?

Sample code could work like this:

import turtle

sc = turtle.Screen()
sc.addshape("./car.png", rotate_image_shape=True)

t = turtle.Turtle()
t.shape("./car.png")

def handle_click(x,y):
    t.setheading(t.towards(x,y))
    t.goto(x,y)

sc.onclick(handle_click)

turtle.mainloop()

so unless you explicitly say that you want to rotate image shape, it would work as it used to.

I did some research and implemented sample solution here:
main...kbialowas:cpython:tilt-turtle-transformation

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

If it works submit a pr if you want

I checked it on my own scripts and demos from Lib/turtledemo directory. Looks like everything works fine. Posted a PR.
