// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-03-25: Mouse cursor is properly restored if changed by user app/code while using glfwSetInputMode(..., GLFW_CURSOR_DISABLED) or ImGuiConfigFlags_NoMouseCursorChange. Amend change from 2025-12-10.
// 2026-02-10: Try to set IMGUI_IMPL_GLFW_DISABLE_X11 / IMGUI_IMPL_GLFW_DISABLE_WAYLAND automatically if corresponding headers are not accessible. (#9225)
// 2025-12-12: Added IMGUI_IMPL_GLFW_DISABLE_X11 / IMGUI_IMPL_GLFW_DISABLE_WAYLAND to forcefully disable either.
// 2025-12-10: Avoid repeated glfwSetCursor()/glfwSetInputMode() calls when unnecessary. Lowers overhead for very high framerates (e.g. 10k+ FPS).
