[threehymns]

Pull Request

Description

This PR makes SCREEN_WIDTH and SCREEN_HEIGHT take the scale of the monitor into account by dividing the resolution by the scale. The screenshots are with a 4k monitor with the monitor scale set to 2.0. (equals a final width and height of 1920x1080). The AGS overview scale is left at the default.
