    Method
    Description
    Vec2
    getCenter()
    center of the viewport.
    Vec2
    getExtents()
    This is the half-width and half-height.
    void
    getScreenToWorld(Vec2 argScreen, Vec2 argWorld)
    takes the screen coordinates (argScreen) and puts the corresponding world coordinates in argWorld.
    void
    getScreenVectorToWorld(Vec2 argScreen, Vec2 argWorld)
    Transforms the given directional screen vector back to the world direction.
    Mat22
    getTransform()
    gets the transform of the viewport, transforms around the center.
    void
    getWorldToScreen(Vec2 argWorld, Vec2 argScreen)
    takes the world coordinate (argWorld) puts the corresponding screen coordinate in argScreen.
    void
    getWorldVectorToScreen(Vec2 argWorld, Vec2 argScreen)
