174 of the contact area and approaching tool, respectively.
222 The ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a
245     tool. This should be understood as the size of the tool itself. The
246     orientation of the contact and the approaching tool are assumed to be the
251     tool. Omit if circular [#f4]_.
296     The surface X coordinate of the center of the approaching tool. Omit if

301     The surface Y coordinate of the center of the approaching tool. Omit if the
302     device cannot distinguish between the intended touch point and the tool
306     from the position of the tool. If both positions are present, the major
307     tool axis points towards the touch point [#f1]_. Otherwise, the tool axes are
