If you look at immediate-mode UI systems like Dear ImGui, those provide vertices, indices and a command list for rendering in each frame, and it's very easy to render those commands through all existing 3D APIs. For instance here is an example of such a render function, it's just 50 lines of C, implemented on top of slim cross-platform headers with support for Windows, Linux, macOS, iOS, Android and WASM: https://github.com/floooh/sokol-samples/blob/0576ed914290a35... (this is from this demo which is 513 KBytes all in all: https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp...) With such a bloat-free UI system you can create statically linked single-exes with embedded font data and shaders in a few hundred KBytes, and people are starting to use this for "
