imgui-rs 1.47.0

IMGUI-RS provides Rust bindings for IMGUI, a bloat-free intermediate mode GUI library for C/C++. IMGUI outputs vertex buffers that you can render in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained. IMGUI does away with state synchronization by requiring the application to explicitly pass all state required in real-time. The user interface only retains the minimal amount of state required to facilitate the functionality required by each type of widget supported by the system.

// ImGui GLFW binding with OpenGL3 + shaders
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
// https://github.com/ocornut/imgui
