Each imgui_impl_X.cppm builds one backend as module imgui.impl.X, following the same layout as imgui.cppm. The global module fragment holds the platform and graphics API headers, using the same conditions as the backend's .cpp. The purview imports std.compat and imgui and includes the backend header. The .cpp goes in 'module :private;'. The backend header includes imgui.h, but its declarations already come from 'import imgui;' and must not be redeclared in this module. Module units therefore define IMGUI_CXX_MODULE_IMPORTED, which makes imgui.h contribute only its macros. Usage: 'import imgui; import imgui.impl.glfw;'. Link the module library in place of the backend .cpp.
