Hi, > 1) Is there CreateJS-licensed source in the source package?
EaselJS and TweenJS are part of the CreateJS project so that’s probably a yes. Either way there's no harm in mentioning it. > 3) License for svg.js.

Yes IMO there are blocks of code that look like they may of been copied from Shumway or perhaps elsewhere. There's no issue here if it was copied as long where it was copied from has an Apache compatible license. The code is a little odd stylistically. For instance the use of brackets in this line in Matrix.as result_b = result_b + (this.a * m.b + this.b * m.d); Doing a google search for this shows the same code (and the rest of the function) from a decompiled version of the Flash Player. Now again I don’t know that is the original source of the code in Matrix.as, and it may not be the case. Would Adobe allowed us to use decompiled code from the Flash Player and claim it’s Apache licensed? If you look at Vector.as it has some code commented out that starts with "if(watson(3109405))”. Why would that be there if it was a recent implementation from scratch based on the API? Again ether may be a reason for it’s existence but currently we don’t know. BTW it looks like Lizhi's code is MIT licensed [2] not Apache. Should it have Apache headers on it in the repo? No issue either way just asking. > Especially if, as I understand it, that APIs are not copyrightable? We’re talking implementation not API.
