Below is my poor man's getVisibleBounds. I'm using this so that my custom text

on the right track - I was surprised that my web search for getVisibleBounds() 
came up so empty. If nobody points out my idiocy, I'm going to put this in a

What is the JFX equivalent of JComponent.getVisibleRect() - and is there a way 
to get a notification when it changes?
