Drawing slides when orientation changes

[alperkirdok]

Hello there,

First of all, I'd like to thank you for developing and open sourcing this project. It has been immensely useful to us. There is one slight issue. After drawing lines and changing the orientation of the phone to landscape, the lines do rotate, but jump when a new line is added.
I've looked into it a bit but couldn't solve it. If anybody has any idea how I can solve this issue, please let me know.
