/**
* Class method to enable visualization of an ASImageNode's image size. For app debugging purposes only.
* @param enabled Specify YES to turn on this debug feature when messaging the ASImageNode class.
* Enables an ASImageNode debug label that shows the ratio of pixels in the source image to those in
* the displayed bounds (including cropRect). This helps detect excessive image fetching / downscaling,
* as well as upscaling (such as providing a URL not suitable for a Retina device). For dev purposes only.
* @param enabled Specify YES to show the label on all ASImageNodes with non-1.0x source-to-bounds pixel ratio.
