Whether to scale the slider to fit target size.
By default, the final display size of the slider will be the size of Outer Container size. If this option is enabled, the final display size of the slider is up to the 'Responsive' options, and it will scale while window resizing.
Note jssor slider will always keep aspect ratio while scaling.
Assuming that responsive options are specified as below,
Scale To: Parent Container Width (width of parent container of the slider)
And Adjust: -20
Then the slider will scale width to ('Parent Container Width' - 20), the width will be no less than 300 and no more than 1000.
