47 * Defines a move operation through a range.
48 *
49 * A move operation is determined by three functions:
50 * - Two 'move' functions, used to indicate in which direction the beginning and the end of a range
51 * are going during the operation. These functions will be:
52 * -- {<- / <-} for pan left
53 * -- {-> / ->} for pan right
54 * -- {-> / <-} for zoom in
55 * -- {<- / ->} for zoom out
56 * - One 'max move' functions, used to compute the max delta at which the operation can move a
57 * range, according to a max range. For exemple, for a range of {1, 5} and a max range of {0, 10},
58 * max deltas will be:
59 * -- {0, 4} for pan left
60 * -- {6, 10} for pan right
61 * -- {3, 3} for zoom in
62 * -- {0, 6} for zoom out (same spacing left and right)
