This class represents the active viewport region in a display window. It contains the screen-space size of the window as well as the origin and size of the viewport within the window. By default, the viewport is the same as the full window. Methods allow the viewport to be set either in terms of screen-space pixels or as normalized coordinates, where (0,0) is the lower-left corner of the window and (1,1) is the upper-right corner.
