License

[antifermion]

I'm currently planning to write an open source cross platform application and I think skia would be a good fit. terramach seems like an excellent starting point for the GUI. Unfortunately, the GPL prevents me from using it, because GPL applications cannot be used in the iOS App Store. It would be great of terramach would be available under a slightly more permissive license such as the MPL (license used by firefox, also copyleft, but only on a "file level", so users would only required to publish modifications to the library).

I'm aware this is a big ask, and can totally understand if you are not willing to do this. Great work on terramach nevertheless.
