// multimon.h -- Stub module that fakes multiple monitor apis on Win32 OSes
// without them.
//
// By using this header your code will get back default values from
// GetSystemMetrics() for new metrics, and the new multimonitor APIs
// will act like only one display is present on a Win32 OS without
// multimonitor APIs.
//
// Exactly one source must include this with COMPILE_MULTIMON_STUBS defined.
