How to: Changing display resolution
The display resolution is controlled by this line:

https://github.com/sickcodes/Docker-OSX/blob/master/custom/config-nopicker-custom.plist#L819

Instead of mounting that disk, Docker-OSX will generate a new `OpenCore.qcow2` by using this one cool trick:

```bash
-e GENERATE_UNIQUE=true \
-e WIDTH=800 \
-e HEIGHT=600 \
```

To use `WIDTH`/`HEIGHT`, you must use with either `-e GENERATE_UNIQUE=true` or `-e GENERATE_SPECIFIC=true`.

It will take around 30 seconds longer to boot because it needs to make a new boot partition using `libguestfs`.

```bash
-e GENERATE_SPECIFIC=true \
-e WIDTH=1920 \
-e HEIGHT=1080 \
-e SERIAL="" \
-e BOARD_SERIAL="" \
-e UUID="" \
-e MAC_ADDRESS="" \
```
