* clutter/win32/clutter-backend-win32.c
	(clutter_backend_win32_init): Added a call to
	timeBeginPeriod. Without this the frame rates are terrible because
	the glib timeouts are not accurate enough. However this requires
	Glib >= 2.16.0 to take any effect because of a change in the way
	g_poll is implemented. See revision 6597 of glib.
	(clutter_backend_win32_finalize): Added a call to timeEndPeriod.

	* configure.ac: Added -lwinmm to the library dependencies for the
	Win32 backend.
