Hi Uwe,

Could the following submitted patches be applied to the Qwt project?

https://sourceforge.net/p/qwt/patches/67/
https://sourceforge.net/p/qwt/patches/68/
https://sourceforge.net/p/qwt/patches/69/
https://sourceforge.net/p/qwt/patches/70/

They don't change existing behavior yet allow more extensibility of the
library.

Regards,
Povilas
