autojs屏幕控件scrollable属性为false时如何滚动屏幕（滑动屏幕）

function RollDown(){
    let delay1 = delay2 = 0
    let duration1 = duration2 = 300
    let x1 = x2  = device.width/2*0.9
    let x3 = x4 = device.width/2*1.1
    let y1 =y3=  device.height*0.7
    let y2 = y4 = device.height*0.3
    gestures([delay1, duration1, [x1, y1], [x2, y2]], [delay2, duration2, [x3, y3], [x4, y4]])

}

function RollUp(){
    let delay1 = delay2 = 0
    let duration1 = duration2 = 300
    let x1 = x2  = device.width/2*0.9
    let x3 = x4 = device.width/2*1.1
    let y1 =y3=  device.height*0.3
    let y2 = y4 = device.height*0.7
    gestures([delay1, duration1, [x1, y1], [x2, y2]], [delay2, duration2, [x3, y3], [x4, y4]])
}

RollDown函数可实现下滚，RollUp函数上滚。gesture为多手势同时模拟，格式为：

gestures([delay1, duration1, [x1, y1], [x2, y2], ...], [delay2, duration2, [x3, y3], [x4, y4], ...], ...)

这里用gesture模拟双指滑动
