Tor Lillqvist 93a5db1511 Bug 496958 - Wacom Bamboo Doesn't Function with GTK apps in Win32 
2008-05-13  Tor Lillqvist  <tml@novell.com>

	Bug 496958 - Wacom Bamboo Doesn't Function with GTK apps in Win32

	* gdk/win32/gdkinput-win32.c (_gdk_input_wintab_init_check): Set
	the "packet rate" of devices to zero instead of 50. This is
	reported to help significantly with Wacom tablet behaviour in GIMP
	and Inkscape. Patch from Thomas Bleeker.
