Enumerator
KeepCurrent	The viewport size is unchanged (this is the default). The viewport is unchanged, and the view contents are resized to match the viewport aspect ratio.
RelativeRect	The viewport is resized to the same size, relative to the available area, that is specifed in viewPortInfo.
AspectRatio	The viewport is resized to match the aspect ratio of the viewInfo.
Size	The viewport is resized to match the exact size specifed in viewPortInfo.
SizeAndPosition	The viewport is resized to match the exact size specified in viewPortInfo, and moved to the position specified as well.
