Kivy canvas - fast drawing - polylines
<p>Tell me please, if drawing in Kivy Canvas fast, I get very acute, 
polylines figure, but if drawing very slow, then I get smooth lines.</p>

<pre><code>    ...

    def on_touch_down(self, touch):
        if Widget.on_touch_down(self, touch):
            return True
        print(touch.x, touch.y)
        with self.canvas.before:
            Color(*get_color_from_hex('#0080FF80'))
            Line(circle=(touch.x, touch.y, 2), width=2)
            touch.ud['current_line'] = Line(points=(touch.x, touch.y), width=2)

    def on_touch_move(self, touch):                               
        if 'current_line' in touch.ud:
            touch.ud['current_line'].points += (touch.x, touch.y)
    ...
</code></pre>

<p>This is my example:</p>
