Currently Strict Finger Placement

So I was digging through the source code attempting to figure out how to
resolve this but got lost.

The main issue I am encountering is that when using this library the function
calls are only triggered if all 3 fingers are lined up horizontally on the
trackpad which makes it really hard to trigger. <<-- most important part of
this bug report. 

I am using a Macbook pro 2010 built-in trackpad running elementary os. 

I have 3 finger swipe up tied to super+Up and as a test I had it tied to just a
single letter in a text document. It seems that the placement of the fingers on
the trackpad determine if it's triggered. The natural position is a triangular
pattern for the 3 fingers.

It would be nice in the configuration to be able to set the length of the swipe
gesture and maybe a flag to make finger position not important. 

Essentially if any 3 fingers in any spot are on the trackpad (or even defined
spots, I don't know how that would work in the config) and the group moves a
certain direction and distance at a certain speed threshold. 

That would open up a lot of different possibilities for fast swipe vs slow
swipe. swipe to top right or top left. Ect.
