      IMHO, the poor current state of 2D vector graphics rendering is the elephant in the room that too many people focused on app perf ignore.

      I guess it’s because UI/vector graphics is hard and the big players are all invested in their legacy codebases, so they put off the work.

      What of Skia? I know it’s what Google uses but I don’t know too much about it beyond that.

      Skia is a giant, old codebase that is trying to retrofit a GPU backend without changing the API, with the results one would expect from this

      Are there some frequent conceptual problem with APIs that you see as impeding GPU native implementations?

      You want an interface that allows the implementation to aggressively batch, use the Z-buffer, and do out-of-Z-order rendering.

          what about AA-artifacts while rendering overlapped strokes? That's one issue I encountered with SVG: https://lists.w3.org/Archives/Public/www-svg/2015Jun/0025.html …

          QML/QtQuick does batching nicely and has an env. var. that allows visualization of what is batched together.
