Now you can add and remove lines in the same option/toggle. I forgot to mention it outright but to use this mode, you need to select a point and click on the first orange outline. In the upcoming updates, there will be icons for these buttons to indicate their function
When in "line mode", the points/circles will change into rectangles. This is one part in attempting to indicate to the user that this element is clickable without telling them (show don't tell)
Created the Icon class to be our main point object, which is mainly represented as a circle. The old Circle class is left in for possible future updates. The Icon class is based on the new Rect class, which is also left in.
Added shadows to our Icon objects to add more detail. In the future, all visual objects need this change
