 // cacheRatio* is a ratio that determines the amount of pixels to cache. The

 // ratio is multiplied by the viewport width or height to get the displayport's

 // width or height, respectively.

 // (divide integer value by 1000 to get the ratio)

 //

 // For instance: cachePercentageWidth is 1500

 //               viewport height is 500

 //               => display port height will be 500 * 1.5 = 750
