I found something that works well. It is actually an adaptation of
something someone else sent on this list before.
I create two ImageComponent2D objects in my code. Both point to the same
BufferedImage, and are by-reference. I also have a variable that toggles
which ImageComponent2D I'm currently using.
Initially, I set my Texture2D to point to the first ImageComponent2D.
Every time I update my BufferedImage, I switch my control variable to the
other ImageComponent2D, call .set(bufferedImage) on it (which I'm allowed to
do because it's not live at that moment), then I call Texture2D.setImage()
with the new ImageComponent2D object.
It works very well, actually! :) I am very pleased with it.
