// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2023-11-13: Updated for recent SDL3 API changes.
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
// 2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391)
// 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
