/**
* Defines a move operation through a range.
*
* A move operation is determined by three functions:
* - Two 'move' functions, used to indicate in which direction the beginning and the end of a range
* are going during the operation. These functions will be:
* -- {<- / <-} for pan left
* -- {-> / ->} for pan right
* -- {-> / <-} for zoom in
* -- {<- / ->} for zoom out
* - One 'max move' functions, used to compute the max delta at which the operation can move a
* range, according to a max range. For exemple, for a range of {1, 5} and a max range of {0, 10},
* max deltas will be:
* -- {0, 4} for pan left
* -- {6, 10} for pan right
* -- {3, 3} for zoom in
* -- {0, 6} for zoom out (same spacing left and right)
