Thank you very much (impressive; I would probably need to use it under Wine ).
Thanks, but you should thank Boian first of all. He is the author of the library, I only introduced minor corrections related to FPC support.
I just tested both demos under Wine on Xubuntu 18.04. Wine has big problems with anti-aliasing, curve filling, gradients and probably also with other operations. So generally, I recommend it only for Windows.
