Instead of defining new symbols for the windowing systems enabled at
configure time, we can reuse the same symbols for both the compile time
and run time checks, e.g.:
#ifdef CLUTTER_WINDOWING_X11
if (clutter_check_windowing_backend (CLUTTER_WINDOWING_X11))
/* use the clutter_x11_* API */
else
#endif
#ifdef CLUTTER_WINDOWING_WIN32
if (clutter_check_windowing_backend (CLUTTER_WINDOWING_WIN32))
/* use the clutter_win32_* API */
#endif
This scheme allows us to ensure that the input system namespace is free
for us to use and select at run time in later versions of Clutter.
