CSkiaSwift - Swift classes wrapper for Skia's C API

Skia's C API is very limited and not actively developed.

Please use SkiaSwift which is based on SkiaSharp's C API. It has much more features.

See:

• https://github.com/apple/swift-package-manager/blob/master/Documentation/PackageDescription.md
