The function getAxis should be improved

[linweilian03]

Run command "synclient -l " , it shows that (part of the result):
LeftEdge = 1132
RightEdge = 5690
TopEdge = 919
BottomEdge = 4888
This means the synclient believes that my touchpad is 5690-1132=4558 wide, and 4880-919=3961 high.
So the xswipe believe that the ratio of width:height=4558:3961=1.15.
However, I used a ruler to physically measure my touchpad. The ruler shows that my touchpad is actually 8.2cm wide and 4.8cm high. The ratio of width:height is actually 8.2:4.8=1.7.
So the xswipe make a mistake in judging your swipe gesture is vertical or horizontal.
In my example, the xSwipe is more likely to take some horizontal gesture as vertical gestures. So I change the code of getAxis
" if($xDist > $yDist)"
to
" if(1.5*$xDist > $yDist)"
Now, it's much better. Maybe some parameters can be added, such as width, height , to solve this problem.
