	* gdk/win32/gdkglobals-win32.c: Set _gdk_input_ignore_wintab to
	FALSE, thus enabling tablet input by default.

	* gdk/win32/gdkmain-win32.c (_gdk_windowing_args): Accept the
	--use-wintab option again (but without effect, as this is now the
	default, see above). (#153788)

	* modules/input/gtkimcontextime.c: Numerous changes.

	Remove the ifdef UNICODE conditionals. Always use the
	wide-character Imm* API. It is present also in Windows 98 and
	Me. (Not Windows 95, but I think we don't care about that.) Using
	the multibyte API wouldn't work anyway on systems where the system
	codepage doesn't support the language the user uses an IME for, so
	for instance I wouldn't be able to test this module on my English
	Windows 2000 although I do have C, J and K IMEs available.

	Guard against IMM not being active, always check ImmGetContext()
	returning NULL. Work to some extent even without any IME. Fixes
	#153800 at least partially.

	* modules/input/imime.c (ime_info): Rename to "ime" to match the
	naming pattern of other input modules. Make it default for
	ja:ko:zh only.
