easeIn expression description:
Description: easeIn(x,x1,x2,y1,y2): returns an ease-in interpolation between y1 and y2. Returns y1 when x
It probably should say:
Description: easeIn(x,x1,x2,y1,y2): returns an ease-in interpolation between y1 and y2. Returns y1 when x <x1.
But that is just weird way to explain easIn operation.
Shouldn`t easeOn be called easeOut?
easeInOut description also is not clear:
... Returns y1 when x x2
Apart from these notes operators work well and I like them!
