First off, a really big thank you for making it possible to distribute my Mapton application in this way.

Having published my first attempt a while back, it’s now time to make an update.  
While playing around with appimagetool and jlink regarding compression I noticed that the more I compress my Custom Runtime Image produced with [jlink](https://docs.oracle.com/en/java/javase/14/docs/specs/man/jlink.html#jlink-options) the larger my AppImages get, with both gzip and xz.  
`-c ={0|1|2}` or `--compress={0|1|2}`

```
Enable compression of resources:

* `0` : No compression
* `1` : Constant string sharing
* `2` : ZIP

```

How is that?  
I guess one should not include compressed stuff if possible.
