Scaling issue with text/text boxes

[Qiangong2]

Describe the bug
Text and/or text boxes do not scale correctly when you change the resolution in the Tuxemon config. This cuts off longer dialogs on higher resolutions. In addition, a lower resolution gives you a wider field of view (which isn't necessarily an issue itself).

1280x720:

1920x1080:

640x360:

I usually test the game at 1280x720, but it feels like 640x360 may be the optimal resolution to play at due to the scaling issues.
