Description Said Abou-Hallawa 2023-08-15 12:12:51 PDT 
Make DisplayList holds a Vector of DisplayList items. There is no need for the read and write clients anymore. They were used in the past to share the recorded DisplayList items with GPU Process through a ring buffer. After introducing the StreamConnection, using the DisplayList became limited to the TextPainter recording. Simplifying this code will allow replaying back a whole DisplayList in GPU Process all at once.
