/**
* Modifications to be made:
* 1. Two possible modes: free-size windowing and fixed-scale windowing
* !!DONE!! 2. Add and remove the newly added window
* !!DONE!! 3. Expand the width or height of the window by a constant number of pixels
* !!DONE!! 4. Expand the dimension (both width and height) of window by a constant scale (e.g. 0.1)
* !!DONE!! 5. Move the window to left, right, up, and down
