// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2022-XX-XX: Metal: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2022-06-01: Metal: Fixed null dereference on exit inside command buffer completion handler.
// 2022-04-27: Misc: Store backend data in a per-context struct, allowing to use this backend with multiple contexts.
// 2022-01-03: Metal: Ignore ImDrawCmd where ElemCount == 0 (very rare but can technically be manufactured by user code).
// 2021-12-30: Metal: Added Metal C++ support. Enable with '#define IMGUI_IMPL_METAL_CPP' in your imconfig.h file.

or interacting with a game/3D view).
- IO: Fixed input queue trickling of mouse wheel events: multiple wheel events are merged, while
a mouse pos followed by a mouse wheel are now trickled. (#4921, #4821)
- IO: Added io.SetAppAcceptingEvents() to set a master flag for accepting key/mouse/characters
events (default to true). Useful if you have native dialog boxes that are interrupting your
application loop/refresh, and you want to disable events being queued while your app is frozen.
- Windows: Fixed first-time windows appearing in negative coordinates from being initialized
with a wrong size. This would most often be noticeable in multi-viewport mode (docking branch)
when spawning a window in a monitor with negative coordinates. (#5215, #3414) [@DimaKoltun]
@ -146,20 +149,29 @@ Other Changes:
- InputScalar: Automatically allow hexadecimal input when format is %X (without extra flag).
- InputScalar: Automatically allow scientific input when format is float/double (without extra flag).
- Nav: Fixed nav movement in a scope with only one disabled item from focusing the disabled item. (#5189)
- Nav: Fixed issues with nav request being transferred to another window when calling SetKeyboardFocusHere()
and simultaneous changing window focus. (#4449)
- IsItemHovered(): added ImGuiHoveredFlags_NoNavOverride to disable the behavior where the
return value is overriden by focus when gamepad/keyboard navigation is active.
- InputText: Fixed pressing Tab emitting two tabs characters because of dual Keys/Chars events being
trickled with the new input queue (happened on some backends only). (#2467, #1336)
- InputText: Fixed a one-frame display glitch where pressing Escape to revert after a deletion
would lead to small garbage being displayed for one frame. Curiously a rather old bug! (#3008)
- InputText: Fixed an undo-state corruption issue when editing main buffer before reactivating item. (#4947)
- InputText: Fixed an undo-state corruption issue when editing in-flight buffer in user callback.
(#4947, #4949] [@JoshuaWebb]
- Tables: Fixed incorrect border height used for logic when resizing one of several synchronized
instance of a same table ID, when instances have a different height. (#3955).
- Tables: Fixed incorrect auto-fit of parent windows when using non-resizable weighted columns. (#5276)
- Tables: Fixed drawcall merging of last column. Depending on some unrelated settings (e.g. BorderH)
merging drawcall of the last column didn't always work (regression since 1.87). (#4843, #4844) [@rokups]
- Inputs: Fixed IsMouseClicked() repeat mode rate being half of keyboard repeat rate.
- ColorEdit: Fixed text baseline alignment after a SameLine() after a ColorEdit() with visible label.
- Menus: Adjusted BeginMenu() closing logic so hovering void or non-MenuItem() in parent window
always lead to menu closure. Fixes using items that are not MenuItem() or BeginItem() at the root
level of a popup with a child menu opened.
- Menus: Menus emitted from the main/scrolling layer are not part of the same menuset as menus emitted
from the menu-bar, avoiding accidental hovering from one to the other. (#3496, #4797) [@rokups]
- Stack Tool: Added option to copy item path to clipboard. (#4631)
- Settings: Fixed out-of-bounds read when .ini file on disk is empty. (#5351) [@quantum5]
- DrawList: Fixed PathArcTo() emitting terminating vertices too close to arc vertices. (#4993) [@thedmd]

- Demo: Add better demo of how to use SetNextFrameWantCaptureMouse()/SetNextFrameWantCaptureKeyboard().
- Metrics: Added a "UTF-8 Encoding Viewer" section using the aforementioned DebugTextEncoding() function.
- Metrics: Added "InputText" section to visualize internal state (#4947, #4949).
- Misc: Fixed calling GetID("label") _before_ a widget emitting this item inside a group (such as InputInt())
from causing an assertion when closing the group. (#5181).
- Misc: Fixed IsAnyItemHovered() returning false when using navigation.

// Instead we don't treat Popup specifically (in order to consistently support menu features in them), maybe the first child menu of a Popup
