[SpinView.|<containerId>_spinView.]enableHD=always|never|limit[, * number *]
Enable, limit or disable optimization for devices where devicePixelRatio is greater than 1 , that is devices with a high-density display like iPhone4 and similar devices. If active then the component limits the size of the IS image request as if the device only had a pixel ratio of 1 and therefore reducing the bandwidth.
If using the limit setting, the component enables high pixel density only up to the specified limit.
