  USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS
  ------------------------------------------
  - The gamepad/keyboard navigation is fairly functional and keeps being improved.
- - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse!
- - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787
+ - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PlayStation, Switch, Xbox) without a mouse!
  - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
  - Keyboard:
-    - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
-      NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays.
-    - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag
-      will be set. For more advanced uses, you may want to read from:
+    - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
+    - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard),
+      the io.WantCaptureKeyboard flag will be set. For more advanced uses, you may want to read from:
        - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
        - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
        - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
       Please reach out if you think the game vs navigation input sharing could be improved.

-         0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
-    - We use a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
-      Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
+    - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
+    - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.
+      For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.
+      Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).

+                        - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[].
+ - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete).
+ - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary.
+ - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO.
+ - 2022/01/20 (1.87) - inputs: reworded gamepad IO.

+ - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used).
+ - 2022/01/17 (1.87) - inputs: reworked mouse IO.

+                     - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.
+ - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum.

 // Implemented features:
 //  [X] Platform: Clipboard support.
+//  [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: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
 //  [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.

+//  2022-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
+//  2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
+//  2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
+//  2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
+//  2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago)with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
+//  2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
+//  2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
+//  2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
+//  2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
+//  2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
+//  2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
 //  2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().

+- 2021/07/30 (0.12) - The offset argument of `PlotXG` functions was been removed. Implement offsetting in your getter callback instead.
 - 2021/03/08 (0.9)  - SetColormap and PushColormap(ImVec4*) were removed. Use AddColormap for custom colormap support. LerpColormap was changed to SampleColormap.
                       ShowColormapScale was changed to ColormapScale and requires additional arguments.
 - 2021/03/07 (0.9)  - The signature of ShowColormapScale was modified to accept a ImVec2 size.
