> Since GPUs are good at drawing 3D scenes, and since 3D scenes seem “more complicated” than 2D scenes, it may feel like a natural conclusion that GPUs should handle 2D trivially. They do not. While not trivial, nanovg shows that it can be done reasonably well. At least well enough for a GUI. Thankfully a GUI doesn't need a very advanced 2D rendering engine (see Dear Imgui or egui). Vector art apps can write their own engines.
