Almost all non Apple touchpads have visible markings for software button areas, so limit clickfinger behavior to Apple clickpads, and implement software button areas for others. This is a slightly fancier implementation than the simplest model and ported over from libtouchpad. It implements a state machine for the software buttons with left and right buttons currently implemented. Buttons are oriented left-to-right, in a horizontal bar. No random button placement allowed. In general, the procedure is: - if a finger sets down in the left button area, a click is a left click - if a finger sets down in the right button area, a click is a right click - if a finger leaves the button area, a click is a left click - if a finger starts outside the button area, a click is a left click Two timeouts are used to handle buttons more smoothly: - if a finger sets down in a button area but "immediately" moves over to a different area, that area takes effect on a click. - if a finger leaves a button area and "immediately" clicks or moves back into the area, the button still takes effect on a click. - if a finger changes between areas and stays there for a timeout, that area takes effect on a click. Note the button area states are named BOTTOM_foo to make it easier to later add support for a top button area such as can be found on the Thinkpad [2-5]40 series.
