Documentation

The ancillary tool being tracked, or nil.

If non-nil, this is a vector of ten elements: the ID of the touch point being tracked, the window where the touch began, a cons holding the initial position of the touch point, and the last known position of the touch point, all in the same format as in touch-screen-current-tool, the distance in pixels between the current tool and the aforementioned initial position, the center of the line formed between those two points, the ratio between the present distance between both tools and the aforesaid initial distance when a pinch gesture was last sent, and three elements into which commands can save data particular to a tool.

The ancillary tool is a second tool whose movement is interpreted in unison with that of the current tool to recognize gestures comprising the motion of both such as "pinch" gestures, in which the text scale is adjusted in proportion to the distance between both tools.
