Question: how does initializing imgui + raylib work?

[tdgroot]

In the template, ImGui is initialized with the following code:

    InitWindow(SCREEN_WIDTH, SCREEN_HEIGHT, "Window Title");

    ImGui::CreateContext();      
    ImGui::StyleColorsDark();

    ImGui_ImplOpenGL3_Init();    
    ImGui_ImplRaylib_Init();

When I try that, the ImGui_ImplOpenGL3_Init call fails when it calls the glGetIntegerv() function to fetch the OpenGL versions. To clarify: rendering with raylib works just fine and the PLATFORM_DESKTOP and GRAPHICS_API_OPENGL_33 constants are defined.

Is there a missing step in the template?

Usually it's necessary to also call ImGui_ImplGlfw_InitForOpenGL(window, true); <- which binds the glfw context to ImGui?

Anyway, I'm interested if there's more to it than described in the template, because I can't seem to get it to work!
