Normalized Mouse Position

This code sample shows how you can create a DataType/Vector2 representing the Mouse object’s position on screen (Mouse/X|X and Mouse/Y|Y) and the size of the screen itself (Mouse/ViewSizeX|ViewSizeX and Mouse/ViewSizeY|ViewSizeY). Using these, you can normalize the position of the mouse on-screen such that the top-left just under the topbar maps to (0, 0) and the bottom-right maps to (1, 1). This normalized position is calculated and printed as the mouse moves using the Mouse/Move|Move event.
