That explains, why, there initially certain features of Cairo, that not exposed by Athens. It is not because we can't or just don't care.. we do.. But only after we can see that it consistent with rest of API and can be easily implemented on most of other potential backends. Yes, i am talking about that damn 'minimal common denominator' problem. :)
Oh, and also i forgot to mention, that there could be also 2 more potential backends: - OpenVG and - Quartz, that is a vector graphics library for Mac OS On 6 April 2016 at 11:23, Igor Stasenko <[email protected]> wrote: > > > On 6 April 2016 at 11:14, Thierry Goubier <[email protected]> > wrote: > >> >> >> 2016-04-06 10:07 GMT+02:00 Igor Stasenko <[email protected]>: >> >>> >>> >>> On 6 April 2016 at 10:35, Nicolai Hess <[email protected]> wrote: >>> >>>> >>>> I made some fixes for AthensBalloon (not all are integrated yet, some >>>> parts are just experimental and needs more tests), the idea is to have >>>> AthensBalloon at least not crash or throwing errors, even if not all >>>> features are supported. >>>> >>> >>> Much, much, much appreciated.
