Renpy Mac apps remember last screen size and use it

Problem

When I change the size of the game screen, people who've run the demo on their computer will not see the updated size.

So far this has been seen on Macs.

Reproduction Steps

1. Create a new project. Set the window size in options.rpy to be 800x600.
2. Launch the project.
3. Quit the project.
4. Alter the options.rpy to be 1280x768.
5. Launch the project again.

Now the window is of the right ratio, but it's only 800 wide.

Solution for users is to go to preferences and click windowed mode. This should fix the size.
Solution for developers is to settle on a screen res early >_>
