    I’m continually sad that Skia is killing all other vector graphics libraries, given how poor its documentation is, how difficult it is to build, etc. :( Especially since Microsoft is effectively deemphasizing D2D (which is excellent). Cairo needs more investment.

        Edge moving to Chromium and Chromium taking patches to build with MSVC while Skia upstream removes SIMD support when compiling with GCC and MSVC is an interesting situation.

        Wow! If I were MS I’d just use fork Chromium to use D2D.

        How do Skia and Cairo compare? I've only ever used Cairo personally and I found it easy enough for the most part. With good language bindings too.

        Skia is way ahead in terms of performance and GPU support. Sad, because Cairo is much better of an open source citizen, IMO :(

        Chrome would never use Cairo as it’s LGPL. I remember doing an audit of Chromium dependencies and they are all ZLIB/MIT/BSD. At one point there was an http://ffmpeg.so  exception. One of the reasons is Google static links for better load time and runtime perf (no PLTs).

        Interesting, hadn’t considered the licensing issues.

        Cairo is excellent at all the little things—documentation, ease of use, contribution culture, portability, open process—that are unimportant for big companies but really important to be a good open source citizen.

        Cairo suffers from all the things other great libs (like gstreamer) suffer from. A gnarly web of dependencies and strict adherence to Autotools and pkg-config. This is also a kind of unfriendliness. I'd never suggest adopting it.

        Cairo build is not actually that bad. It is possible to build cairo standalone. It does use pkg-config but I usually just make a separate CMakeLists.txt. It is problematic distributing in an app for say Android or iOS. Signing and LGPL are not really compatible.
