Lightweight 2D graphics with io2d
summary
io2d is a lightweight C++ 2D graphics reference implementation that claims cross‑platform builds for Windows, OS X, iOS and Linux and is available on vcpkg; it relies on Cairo, GraphicsMagick (PNG), Boost and libpng to build. Examples include a 200‑line Conway's Life running at 30Hz, a 190‑line sprite demo and a 750‑line OpenStreetMap renderer plus an Asteroids clone; code shows how to write custom renderers (Cairo provided, Vulkan/DirectText/OpenGL pluggable) and works as a small, practical graphics API for teaching and casual games.
