Not a feature idea: Just something to be aware of - Blend2D Vector Engine is supremely fast
-
https://blend2d.com/ - Blend2D engine is an open source, permissive Zlib licensed vector rendering engine. What's unique about it is that it is blazingly fast (I tried it in a sandbox) and is very optimised for multithread performance, but does not need GPUs. I've suggested Inkscape to ditch ageing Cairo and adopt it. Just a project to be aware of if you're not already.
Performance benchmarks are here: https://blend2d.com/performance.html - It compares very well against others such as Skia and Cairo.
