 // dear imgui: Platform Backend for Windows (standard windows API for 32 and 64 bits applications)
 // This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
 
 // Implemented features:
 //  [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
 //  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
 //  [X] Platform: Keyboard arrays indexed using VK_* Virtual Key Codes, e.g. ImGui::IsKeyPressed(VK_SPACE).
 //  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
 
 // You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
 // 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

 // - Your own app may already do this via a manifest or explicit calls. This is mostly useful for our examples/ apps.
 // - In theory we could call simple functions from Windows SDK such as SetProcessDPIAware(), SetProcessDpiAwareness(), etc.
 //   but most of the functions provided by Microsoft require Windows 8.1/10+ SDK at compile time and Windows 8/10+ at runtime,
 //   neither we want to require the user to have. So we dynamically select and load those functions to avoid dependencies.
