enclosed by the Left/Right/Top/BottomEdge parameters.
For circular touchpads.
The LeftEdge, RightEdge, TopEdge and BottomEdge parameters are used to
define the edge and corner areas of the touchpad. The parameters split
the touchpad area in 9 pieces, like this:

(area 1) are part of the upper left corner, etc. A good way to find
appropriate edge parameters is to enable the SHMConfig option and run
"synclient -m 1" to see the x/y coordinates corresponding to different
positions on the touchpad.
A tap event happens when the finger is touched and released in a time
interval shorter than MaxTapTime, and the touch and release
coordinates are less than MaxTapMove units apart. A "touch" event
