SchemaPrinter is not extendable

[kurzyx]

Hi,

A while back a PR was accepted that changed the private methods in the SchemaPrinter class to protected. This would allow for extending the SchemaPrinter class.

However, all method calls within this class still use self::, so late static binding does not work resulting in the class not being extendable.

Am I missing something?

No, changing to static seems sensible.

Seems that this was fixed in #747.
