    Good. I added the missing header definition to LCL in r57240.
    Could you please review the revision and eventually fix it, if needed?

r57677
reviewed and fixed. Also added support for the deprecated userSpaceScaleFactor (which was in todo for that)

    How is it done?


respondToSelector instance method
https://developer.apple.com/documentation/objectivec/1418956-nsobject/1418583-respondstoselector?language=objc

or instancesRespondToSelector class method.
https://developer.apple.com/documentation/objectivec/nsobject/1418555-instancesrespondtoselector?language=objc
the later is rarely used.

Thank you.

Ondrej
