* Distortion can occur, and the application may appear stretched or compressed.
*
* - kResolutionNoBorder -
* The entire application fills the specified area, without distortion but possibly with some cropping,
* while maintaining the original aspect ratio of the application.
*
* - kResolutionShowAll -
* The entire application is visible in the specified area without distortion while maintaining the original
* aspect ratio of the application. Borders can appear on two sides of the application.
