// Application Notes
// The effect is initialised and controlled by event calls to function
// zxcScroller('h','tst2','start',1,100,200);
// where:
//  parameter 0 = the mode, for vertical 'v', for horizontal 'h'.                                (string 'v' or 'h')
//  parameter 1 = the unique id name of the scroll container.                                    (string)
//  parameter 2 = (optional) to scroll up/left = negative digit or down/right = positive digit.  (digit, default = -1)
//                may also be used to control the scroll speed.
//  parameter 3 = (optional) the scroll speed (milli seconds).                                   (digits, default = 100)
//  parameter 4 = (optional) the hold delay speed (milli seconds),                               (digits, default = no hold)
//                           may only be used if parameter 3 is 1 or -1.
//  parameter 5 = (optional) the hold position from the left/top (px).                           (digits, default = 0)
//  parameter 6 = (optional) the initial delay before scrolling (milli seconds).                 (digits, default = no auto start)
//
// The first call will initialise the effect.
// Subsequent calls may be used control the effect by updating parameters 2, 3

// To Stop & Start the Scroller
// Function zxcScrollerSS('tst1','v',true) may be used to stop and start the scroller.
// where:
//  parameter 0 = the mode, for vertical 'v', for horizontal 'h'. (string 'v' or 'h')
//  parameter 1 = the unique id name of the scroll container.     (string)
//  parameter 2 = (string) to toggle the rotation between stop and start the scroller. (string)
//  parameter 2 = true to start or false to stop the scroller.    (boolen, default = false)
