[GTK] Add kinetic scrolling

Here you are using the horizonte/vertical data position, but on ::start you only set them if mayV/HScroll are true, meaning you may be reusing the data from another scrolling event (you only initialize the PerAxisData on the constructor). Also, you want to use the original position (on notifyPositionChanged) for a given direction (x/y) if that doesnt change (mayV/HScroll=false) during animation and most probably not invoke animateScroll on that direction.</pre>
