Various layout issues when iPad app is in compact width

[chucks]

Describe the bug
iPad multitasking is enabled in info.plist, but the app has various layout issues when running side by side in compact width.

This is true even with the cube worldScale fix from #126

To reproduce

• Launch the app on iPad and use multitasking to put the app into compact width.
• rotate the iPad etc etc

Expected behavior
Nothing is clipped and screen width is used effectively. It would probably be most effective if the iPad app in compact width used layout metrics similar to the phone app since compact width sizes are fairly similar.

Screenshots/video

some representative examples.

Environment

• iPad, iOS 14.7.1

I'm working on a PR to use the iPhone layout values when running on iPad in compact width.
