Tor Lillqvist d000d2bb6d Add some more GdkDebugFlags, for more fine-grained debugging output
2002-02-13  Tor Lillqvist  <tml@iki.fi>

	* gdk/gdkinternals.h: Add some more GdkDebugFlags, for more
	fine-grained debugging output (mainly used in the Win32 backend).

	* gdk/gdk.c: Corresponding additions to the gdk_debug_keys table.
