// 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.)
// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ for full feature support.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
// [x] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// Issues:
// [ ] Platform: Multi-viewport support: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
// 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.

DOCKING+MULTI-VIEWPORT BRANCH (In Progress)
-----------------------------------------------------------------------
DOCKING FEATURES
(see https://github.com/ocornut/imgui/wiki/Docking for quick intro)
- Added Docking system: [BETA] (#2109, #351)
- Added ImGuiConfigFlags_DockingEnable flag to enable Docking.
Set with `io.ConfigFlags |= ImGuiConfigFlags_DockingEnable;`.
- Added DockSpace(), DockSpaceOverViewport() API.
- Added ImGuiDockNodeFlags flags for DockSpace().
- Added SetNextWindowDockID(), SetNextWindowClass() API.
- Added GetWindowDockID(), IsWindowDocked() API.
- Added ImGuiWindowFlags_NoDocking window flag to disable the possibility for a window to be docked.
Popup, Menu and Child windows always have the ImGuiWindowFlags_NoDocking flag set.
- Added ImGuiWindowClass to specify advanced docking/viewport related flags via SetNextWindowClass().
- Added io.ConfigDockingNoSplit option.
- Added io.ConfigDockingWithShift option.
- Added io.ConfigDockingAlwaysTabBar option.
- Added io.ConfigDockingTransparentPayload option.
- Style: Added ImGuiCol_DockingPreview, ImGuiCol_DockingEmptyBg colors.
- Demo: Added "DockSpace" example app showcasing use of explicit dockspace nodes.
MULTI-VIEWPORT FEATURES
(see https://github.com/ocornut/imgui/wiki/Multi-Viewports for quick intro)
Breaking Changes:
- IMPORTANT: When multi-viewports are enabled (with io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable),
all coordinates/positions will be in your natural OS coordinates space. It means that:
- Reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are _probably_ not what you want anymore.
Use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos).
- Likewise io.MousePos and GetMousePos() will use OS coordinates.
If you query mouse positions to interact with non-imgui coordinates you will need to offset them.
e.g. subtract GetWindowViewport()->Pos.
- IO: Removed io.DisplayVisibleMin, io.DisplayVisibleMax settings (they were marked obsoleted, used to clip within the (0,0)..(DisplaySize) range).
Other changes:
(FIXME: This need a fuller explanation!)
- Added ImGuiPlatformIO structure and GetPlatformIO().
- Similarly to ImGuiIO and GetIO(), this structure is the main point of communication for backends supporting multi-viewports.
- Backend sets functions in ImGuiPlatformIO to manipulate platform windows.
- ImGuiPlatformIO::Monitors is a list of platform monitors (input from backend)
- ImGuiPlatformIO::Viewports is a list of viewports (output from dear imgui)
- Added ImGuiPlatformMonitor to feed OS monitor information in the ImGuiPlatformIO::Monitors.
- Added GetWindowViewport(), SetNextWindowViewport().
- Added GetWindowDpiScale().
- Added GetOverlayDrawList(ImGuiViewport* viewport).
The no-parameter version of GetOverlayDrawList() return the overlay for the current window's viewport.
- Added UpdatePlatformWindows(), RenderPlatformWindowsDefault(), DestroyPlatformWindows() for usage in application setup.
- Added FindViewportByID(), FindViewportByPlatformHandle() for usage by backends.
- Added ImGuiConfigFlags_ViewportsEnable configuration flag and other viewport options.
- Added io.ConfigViewportsNoAutoMerge option.
- Added io.ConfigViewportsNoTaskBarIcon option.
- Added io.ConfigViewportsNoDecoration option.
- Added io.ConfigViewportsNoDefaultParent option.
- Added ImGuiBackendFlags_PlatformHasViewports, ImGuiBackendFlags_RendererHasViewports, ImGuiBackendFlags_HasMouseHoveredViewport backend flags.
- Added io.AddMouseViewportEvent() (optional _even_ for multi-viewport support, tied to ImGuiBackendFlags_HasMouseHoveredViewport flag).
- Expanded ImGuiViewport structure, ImGuiViewportFlags flags.
- Added ImGuiWindowClass and SetNextWindowClass() for passing viewport related hints to the OS/platform back-end.
- Examples: Renderer: OpenGL2, OpenGL3, DirectX9, DirectX10, DirectX11, DirectX12, Vulkan: Added support for multi-viewports.
- Examples: Platforms: Win32, GLFW, SDL2: Added support for multi-viewports.
Note that Linux/Mac still have inconsistent support for multi-viewports. If you want to help see https://github.com/ocornut/imgui/issues/2117.

- Docking: Tabs use their own identifier instead of the Window identifier.

- Docking: Fixed size constraints not working on single window holding on a dock id (still doesn't work on docked windows).
- Docking: Fixed CTRL+TAB back into a docked window not selecting menu layer when no item are on main layer.
- Viewports, IO: Added io.AddMouseViewportEvent() function to queue hovered viewport change (when known by backend).
- Viewports: Relaxed specs for backend supporting ImGuiBackendFlags_HasMouseHoveredViewport: it is now _optional_
for the backend to have to ignore viewports with the _NoInputs flag when call io.AddMouseViewportEvent(). It is
much better if they can (Win32 and GLFW 3.3+ backends can, SDL and GLFW 3.2 backends cannot, they are lacking data).
A concrete example is: when dragging a viewport for docking, the viewport is marked with _NoInputs to allow us
to pick the target viewports for docking. If the backend reports a viewport with _NoInputs when calling the
io.AddMouseViewportEvent() function, then Dear ImGui will revert to its flawed heuristic to find the viewport under.
By lowering those specs, we allow the SDL and more backend to support this, only relying on the heuristic in a few
drag and drop situations rather that relying on it everywhere.
- Viewports: Fixed a CTRL+TAB crash with viewports enabled when the window list needs to appears in
its own viewport (regression from 1.86). (#4023, #787)
- Viewports: Fixed active InputText() from preventing viewports to merge. (#4212)
- Backends: SDL: Added support for ImGuiBackendFlags_HasMouseHoveredViewport now that its specs have been lowered.
- (Breaking) Removed ImGuiPlatformIO::Platform_SetImeInputPos() in favor of newly standardized
io.SetPlatformImeDataFn() function. Should not affect more than default backends.

called after Begin() on a docked window (broken 2021/03/04). (#3851)

- Viewports: Fixed a crash while a window owning its viewport disappear while being dragged.
It would manifest when e.g. reconfiguring dock nodes while dragging.
- Viewports: Fixed unnecessary creation of temporary viewports when multiple docked windows
got reassigned to a new node (created mid-frame) which already has a HostWindow.
- Viewports: Fixed window with viewport ini data immediately merged into a host viewport from
leaving a temporary viewport alive for a frame (would leak into backend).

- docking: B~ Unreal style document system (requires low-level controls of dockspace serialization fork/copy/delete). this is mostly working but the DockBuilderXXX api are not exposed/finished.
- docking: B: when docking outer, perform size locking on neighbors nodes the same way we do it with splitters, so other nodes are not resized.
- docking: B~ central node resizing behavior incorrect.
- docking: B: changing title font/style per-window is not supported as dock nodes are created in NewFrame.
- docking: B- dock node inside its own viewports creates 1 temporary viewport per window on startup before ditching them (doesn't affect the user nor request platform windows to be created, but unnecessary)
- docking: B- resize sibling locking behavior may be less desirable if we merged same-axis sibling in a same node level?
- docking: B- single visible node part of a hidden split hierarchy (OnlyNodeWithWindows != NULL) should show a normal title bar (not a tab bar)

- viewport: use getfocus/setfocus api to synchronize imgui<>platform focus better (e.g imgui-side ctrl-tab can focus os window, OS initial setup and alt-tab can focus imgui window etc.)
- viewport: store per-viewport/monitor DPI in .ini file so an application reload or main window changing DPI on reload can be properly patched for.
- viewport: implicit/fallback Debug window can hog a zombie viewport (harmless, noisy?) > could at least clear out the reference on a per session basis?

//-----------------------------------------------------------------------------
// [BETA] (Optional) This is completely optional, for advanced users!
// 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.

// Demonstrate using DockSpace() to create an explicit docking node within an existing window.
// 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/undocking.
// 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.
