Help me fix two Autohotkey scripts so they'll work well on 4k.

Hello! I'm a Mac user myself, but I'm posting this project in order to help a friend of mine who uses Windows. The problem is this: My friend has written a few Autohotkey scripts, and they looked good when he was using his old 1080p screen. However, he's migrating to a new laptop with a 4k display, and his scripts now look broken. For instance, a script that's supposed to resize a window to 1/2 of the screen will now resize it to a tiny fraction of the screen, and so on. So we need someone to fix his scripts so that all tasks that are dependent on screen resolution will work correctly on his new 4k display. There are the only scripts that need fixting: - One AHK script, which encompasses several resolution-dependent tasks, such as resizing and moving windows. - One EXE that executes only one task: making an image display across the entire screen every 30 minutes. He has asked me not to upload these files for everyone to see, but if you need to see them, contact me and I'll send them to you personally. If you think you can help, prove you've made it to the bottom of this project description by answering this question: If a world war broke out between dogs and cats, which side would you be on?
