167 of the contact area and approaching tool, respectively.
213 The ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a
239 tool. This should be understood as the size of the tool itself. The
240 orientation of the contact and the approaching tool are assumed to be the
246 tool. Omit if circular [4].
296 The surface X coordinate of the center of the approaching tool. Omit if
298 tool itself.
302 The surface Y coordinate of the center of the approaching tool. Omit if the
303 device cannot distinguish between the intended touch point and the tool
307 from the position of the tool. If both positions are present, the major
308 tool axis points towards the touch point [1]. Otherwise, the tool axes are
313 The type of approaching tool. A lot of kernel drivers cannot distinguish
314 between different tool types, such as a finger or a pen. In such cases, the
319 device, because the firmware may not be able to determine which tool is being

377 ellipse, so approximate it with an inscribed circle instead. The tool
380 equal to the tool thickness, and we arrive at the formulas above.
