// Polyphase's Cocoa platform backend for Dear ImGui. Forked from the vendored
// backends/imgui_impl_osx.mm and restructured to match imgui_impl_xcb: the
// engine's NSEvent pump (System_MacCocoa.mm) hands every event to
// ImGui_ImplMac_EventHandler, mouse coordinates are in backing pixels (what
// the engine uses for mWindowWidth/Height), and NewFrame takes DisplaySize
// and DeltaTime from the engine rather than from the view.
//
// The header is ObjC-free so it can be included from C++ TUs; the void*
// parameters are NSView* / NSEvent*.
