* Include more changes(reverts and a fix)
1. Make CupertinoSwitch use BoxShadow.toPaint() so that it respects
the `debugDisableShadows` flag.
2. Increase blue radius on debug banner
3. Only stroke "synthetic shadow" borders if elevation is positive.
Before this change, if CDPATH was set, and you type (from the flutter root) "bin/flutter --version" you would get an error.
This is because the cd command in follow_links was printing the directory Bash chose from the CDPATH to stdout, causing the path to have a newline in it, which understandably confuses the rest of the script.
