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.

```

- On Linux and similar Unixes

```
c++ `sdl2-config --cflags` -I ../.. main.cpp imgui_impl_sdl.cpp ../../imgui*.cpp `sdl2-config --libs` -lGL -o sdl2example
```

- On Mac OS X

```
brew install sdl2
c++ `sdl2-config --cflags` -I ../.. main.cpp imgui_impl_sdl.cpp ../../imgui*.cpp `sdl2-config --libs` -framework OpenGl -o sdl2example
