// If you are new to Dear ImGui and trying to integrate it into your engine, you can probably ignore this for now.
//
// This feature allows you to seamlessly drag Dear ImGui windows outside of your application viewport.
// This is achieved by creating new Platform/OS windows on the fly, and rendering into them.
// Dear ImGui manages the viewport structures, and the backend create and maintain one Platform/OS window for each of those viewports.
//
// See Glossary https://github.com/ocornut/imgui/wiki/Glossary for details about some of the terminology.
// See Thread https://github.com/ocornut/imgui/issues/1542 for gifs, news and questions about this evolving feature.
//
// About the coordinates system:
// - When multi-viewports are enabled, all Dear ImGui coordinates become absolute coordinates (same as OS coordinates!)
// - So e.g. ImGui::SetNextWindowPos(ImVec2(0,0)) will position a window relative to your primary monitor!
// - If you want to position windows relative to your main application viewport, use ImGui::GetMainViewport()->Pos as a base position.
//
// Steps to use multi-viewports in your application, when using a default backend from the examples/ folder:
// - Application: Enable feature with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// - Backend: The backend initialization will setup all necessary ImGuiPlatformIO's functions and update monitors info every frame.
// - Application: In your main loop, call ImGui::UpdatePlatformWindows(), ImGui::RenderPlatformWindowsDefault() after EndFrame() or Render().
// - Application: Fix absolute coordinates used in ImGui::SetWindowPos() or ImGui::SetNextWindowPos() calls.
//
// Steps to use multi-viewports in your application, when using a custom backend:
// - Important: THIS IS NOT EASY TO DO and comes with many subtleties not described here!
// It's also an experimental feature, so some of the requirements may evolve.
// Consider using default backends if you can. Either way, carefully follow and refer to examples/ backends for details.
// - Application: Enable feature with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// - Backend: Hook ImGuiPlatformIO's Platform_* and Renderer_* callbacks (see below).
// Set 'io.BackendFlags |= ImGuiBackendFlags_PlatformHasViewports' and 'io.BackendFlags |= ImGuiBackendFlags_PlatformHasViewports'.
// Update ImGuiPlatformIO's Monitors list every frame.
// Update MousePos every frame, in absolute coordinates.
// - Application: In your main loop, call ImGui::UpdatePlatformWindows(), ImGui::RenderPlatformWindowsDefault() after EndFrame() or Render().
// You may skip calling RenderPlatformWindowsDefault() if its API is not convenient for your needs. Read comments below.
// - Application: Fix absolute coordinates used in ImGui::SetWindowPos() or ImGui::SetNextWindowPos() calls.
//
// About ImGui::RenderPlatformWindowsDefault():
// - This function is a mostly a _helper_ for the common-most cases, and to facilitate using default backends.
// - You can check its simple source code to understand what it does.
// It basically iterates secondary viewports and call 4 functions that are setup in ImGuiPlatformIO, if available:
// Platform_RenderWindow(), Renderer_RenderWindow(), Platform_SwapBuffers(), Renderer_SwapBuffers()
// Those functions pointers exists only for the benefit of RenderPlatformWindowsDefault().
// - If you have very specific rendering needs (e.g. flipping multiple swap-chain simultaneously, unusual sync/threading issues, etc.),
// you may be tempted to ignore RenderPlatformWindowsDefault() and write customized code to perform your renderingg.
// You may decide to setup the platform_io's *RenderWindow and *SwapBuffers pointers and call your functions through those pointers,
// or you may decide to never setup those pointers and call your code directly. They are a convenience, not an obligatory interface.

// N = ImGui::NewFrame() ~ beginning of the dear imgui frame: read info from platform/OS windows (latest size/position)
// F = ImGui::Begin(), ImGui::EndFrame() ~ during the dear imgui frame
// U = ImGui::UpdatePlatformWindows() ~ after the dear imgui frame: create and update all platform/OS windows
// R = ImGui::RenderPlatformWindowsDefault() ~ render
// D = ImGui::DestroyPlatformWindows() ~ shutdown
// The general idea is that NewFrame() we will read the current Platform/OS state, and UpdatePlatformWindows() will write to it.
//
// The functions are designed so we can mix and match 2 imgui_impl_xxxx files, one for the Platform (~window/input handling), one for Renderer.

// Note: You can use most Docking facilities without calling any API. You DO NOT need to call DockSpace() to use Docking!
// - Drag from window title bar or their tab to dock/undock. Hold SHIFT to disable docking.
// - Drag from window menu button (upper-left button) to undock an entire node (all windows).
// - When io.ConfigDockingWithShift == true, you instead need to hold SHIFT to enable docking.
// About dockspaces:
// - Use DockSpace() to create an explicit dock node _within_ an existing window.
// - Use DockSpaceOverViewport() to create an explicit dock node covering the screen or a specific viewport.
// This is often used with ImGuiDockNodeFlags_PassthruCentralNode.
// - Important: Dockspaces need to be submitted _before_ any window they can host. Submit it early in your frame! (*)
// - Important: Dockspaces need to be kept alive if hidden, otherwise windows docked into it will be undocked.
// e.g. if you have multiple tabs with a dockspace inside each tab: submit the non-visible dockspaces with ImGuiDockNodeFlags_KeepAliveOnly.
// (*) because of this constraint, the implicit \"Debug\" window can not be docked into an explicit DockSpace() node,
// because that window is submitted as part of the part of the NewFrame() call. An easy workaround is that you can create
// your own implicit "Debug##2" window after calling DockSpace() and leave it in the window stack for anyone to use.
