| // dear imgui: Platform Backend for GLFW | 
 | // This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..) | 
 | // (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.) | 
 |  | 
 | // Implemented features: | 
 | //  [X] Platform: Clipboard support. | 
 | //  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'. | 
 | //  [x] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: 3 cursors types are missing from GLFW. | 
 | //  [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE). | 
 |  | 
 | // You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this. | 
 | // Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need. | 
 | // If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp. | 
 | // Read online: https://github.com/ocornut/imgui/tree/master/docs | 
 |  | 
 | // About GLSL version: | 
 | // The 'glsl_version' initialization parameter defaults to "#version 150" if NULL. | 
 | // Only override if your GL version doesn't handle this GLSL version. Keep NULL if unsure! |
