Very interesting and useful, but when I read the title I was hoping it would be something different.

I would love to find some kind of stripped-down vector graphics engine that is fully geared towards real-time rendering of path-based graphics for games. For example to write retro-style games that use 2D vector graphics instead of textured quads. I've been writing a simple game that uses this graphics style, and so far I've been simply using pre-rendered textures for sprites. Being able to directly render these things by composing vector-based layers would allow all kinds of interesting effects and image quality improvements, e.g. seamless scaling morphing, etc. Obviously this would be way, way slower than emulating these things using bitmap textures and/or SDF's for scaling, but for the simple graphics my game is using that should probably be fine, even on mid-range hardware there is plenty of frame time I could dedicate to vector rendering and still hit at least 30fps.
