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]_.
300 The surface X coordinate of the center of the approaching tool. Omit if

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