This is used to quickly test compilation of core imgui files in as many setups as possible.
Because this application doesn't create a window nor a graphic context, there's no graphics output.

**DO NOT USE OPENGL2 CODE IF YOUR CODE/ENGINE IS USING GL OR WEBGL (SHADERS, VBO, VAO, etc.)** <BR>
This code is mostly provided as a reference to learn about Dear ImGui integration, because it is shorter.
If your code is using GL3+ context or any semi modern GL calls, using this renderer is likely to
make things more complicated, will require your code to reset many GL attributes to their initial
state, and might confuse your GPU driver. One star, not recommended.

This support building with Emscripten and targetting WebGL.<BR>
Prefer using that if you are using modern GL or WebGL in your application.

For this example, the main.cpp file exceptionally use helpers function from imgui_impl_vulkan.h/cpp.
