// - The general idea is that several callers register interest in a shortcut, and only one owner gets it.

// Child1 -> call Shortcut(Ctrl+S) // When Child1 is focused, Child1 gets the shortcut (Child1 overrides Parent shortcuts)
// Child2 -> no call // When Child2 is focused, Parent gets the shortcut.
// The whole system is order independent, so if Child1 does it calls before Parent results will be identical.
// This is an important property as it facilitate working with foreign code or larger codebase.
// - Visualize registered routes in 'Metrics->Inputs' and submitted routes in 'Debug Log->InputRouting'.
// - When a policy (except for _RouteAlways *) is set, Shortcut() will register itself with SetShortcutRouting(),
// allowing the system to decide where to route the input among other route-aware calls.
// (* Using ImGuiInputFlags_RouteAlways is roughly equivalent to calling IsKeyChordPressed(key)).
// - Shortcut() uses ImGuiInputFlags_RouteFocused by default. Meaning that a Shortcut() call will register
// a route and only succeed when parent window is in the focus-stack and if no-one with a higher priority
// is claiming the same shortcut.
// - You can chain two unrelated windows in the focus stack using SetWindowParentWindowForFocusRoute().
// - Priorities: GlobalHigh > Focused (when owner is active item) > Global > Focused (when focused window) > GlobalLow.

// - The idea is that instead of "eating" a given input, we can link to an owner id.
// - Ownership is most often claimed as a result of reacting to a press/down event (but occasionally may be claimed ahead).
// - Input queries can then read input by specifying ImGuiKeyOwner_Any (== 0), ImGuiKeyOwner_None (== -1) or a custom ID.
// - Legacy input queries (without specifying an owner or _Any or _None) are equivalent to using ImGuiKeyOwner_Any (== 0).
// - Input ownership is automatically released on the frame after a key is released. Therefore:
// - for ownership registration happening as a result of a down/press event, the SetKeyOwner() call may be done once (common case).
// - for ownership registration happening ahead of a down/press event, the SetKeyOwner() call needs to be made every frame (happens if e.g. claiming ownership on hover).
// - SetItemKeyOwner() is a shortcut for common simple case. A custom widget will probably want to call SetKeyOwner() multiple times directly based on its interaction state.
// - This is marked experimental because not all widgets are fully honoring the Set/Test idioms. We will need to move forward step by step.
// Please open a GitHub Issue to submit your usage scenario or if there's a use case you need solved.

// [EXPERIMENTAL] High-Level: Input Access functions w/ support for Key/Input Ownership
// - Important: legacy IsKeyPressed(ImGuiKey, bool repeat=true) _DEFAULTS_ to repeat, new IsKeyPressed() requires _EXPLICIT_ ImGuiInputFlags_Repeat flag.
// - Expected to be later promoted to public API, the prototypes are designed to replace existing ones (since owner_id can default to Any == 0)
// - Specifying a value for 'ImGuiID owner' will test that EITHER the key is NOT owned (UNLESS locked), EITHER the key is owned by 'owner'.
// Legacy functions use ImGuiKeyOwner_Any meaning that they typically ignore ownership, unless a call to SetKeyOwner() explicitly used ImGuiInputFlags_LockThisFrame or ImGuiInputFlags_LockUntilRelease.
// - Binding generators may want to ignore those for now, or suffix them with Ex() until we decide if this gets moved into public API.
IMGUI_APIboolIsKeyPressed(ImGuiKeykey,ImGuiIDowner_id,ImGuiInputFlagsflags=0);// Important: when transitioning from old to new IsKeyPressed(): old API has "bool repeat = true", so would default to repeat. New API requiress explicit ImGuiInputFlags_Repeat.
// - ImGuiKeyChord = a ImGuiKey optionally OR-red with ImGuiMod_Alt/ImGuiMod_Ctrl/ImGuiMod_Shift/ImGuiMod_Super.
// ImGuiKey_C (accepted by functions taking ImGuiKey or ImGuiKeyChord)
// ImGuiKey_C | ImGuiMod_Ctrl (accepted by functions taking ImGuiKeyChord)
// ONLY ImGuiMod_XXX values are legal to 'OR' with an ImGuiKey. You CANNOT 'OR' two ImGuiKey values.
// - When using one of the routing flags (e.g. ImGuiInputFlags_RouteFocused): routes requested ahead of time given a chord (key + modifiers) and a routing policy.
// - Routes are resolved during NewFrame(): if keyboard modifiers are matching current ones: SetKeyOwner() is called + route is granted for the frame.
// - Route is granted to a single owner. When multiple requests are made we have policies to select the winning route.
// - Multiple read sites may use the same owner id and will all get the granted route.
// - For routing: when owner_id is 0 we use the current Focus Scope ID as a default owner in order to identify our location.
// - TL;DR;
// - IsKeyChordPressed() compares mods + call IsKeyPressed() -> function has no side-effect.
// - Shortcut() submits a route then if currently can be routed calls IsKeyChordPressed() -> function has (desirable) side-effects.
