### Issue description

draw_dashed line fills the ending up instead leaving unpainted, maybe intended to draw more closed dashed rectangles, but i would call this a bug. If its intended the docs should mention this and i would like to see an option to turn this behavior off.
For example to use this for drawing multicolored dashed lines it would be a unwanted.

Below is shown lengths from 1 to 200

### Steps to reproduce

Run this lines to draw dashed lines:

```
	for i in range(0,200,2):
		self.draw_dashed_line(topleft + Vector2(0, i),
		topleft + Vector2(i, i),
		Color(1,1,1,1), 1, 10)
```
