2005-02-02 Tor Lillqvist <tml@novell.com> Implement lazy extended input initialization on Win32, by Robert Ögren. Fixes #163163, possibly #162334. Lazy initialization would be a good idea in any case even if it didn't fix any visible problems, though. The Wacom tablet driver seems to get confused if Wintab is initialized but no window is shown before the process exits. This is the case for some GIMP plug-ins, for instance. * gdk/win32/gdkinput-win32.c (_gdk_input_wintab_init_check): Made non-static (and renamed). (_gdk_input_init): Don't call _gdk_input_wintab_init_check(). * gdk/win32/gdkinput-win32.h: Declare _gdk_input_wintab_init_check(). * gdk/win32/gdkinput.c (gdk_devices_list, gdk_display_list_devices, gdk_input_set_extension_events): Call _gdk_input_wintab_init_check() here instead.
