Besides the implicit x/y assumptions, devices don't have axes. Those are actually provided by the GdkDeviceTool driving the device, and different tools may have different axes. It does not make sense to offer this API that can change beneath someone's feet, we now have gdk_device_tool_get_axes() which is static to the tool.
