Large items with layer exceeding maximum texture size terminate program

Try the simple example below and observe how the program terminates, because it reaches the maximum texture size. I know this is an extreme cause, but terminating the program isn't great for our users. We'd rather get a warning and some visual artifacts.

Rectangle {
    width: 500000
    height: 500000
    layer.enabled: true
} 

In our concrete example, Metal was triggering the program termination and reported a 16k x 16k texture size limit.
