Description
- ImageDisplay is using java.awt.MediaTracker.
According to https://stackoverflow.com/a/7369580/205629 (written in 2010):
MediaTracker was useful in 1995. Back then the primary GUI use of java was Applets, and Applets would usually load images slowly over the network.
...
These days you can typically load images synchronously, and it is best to use ImageIO.
- ImageDisplay creates a new thread for each image to be loaded. We can use
MainApplication.worker
- ...?
