Oh, it's worse than before - it crashes the MacVM (log attached for 
John)! After commenting out test8BitDisplay the tests run with this 
result: 24 run, 23 passed, 0 failed, 1 error. The error is in 
test4BitDisplay (error out of bounds in ZipEncoder. But the tests seem 
to be wrong too, as none of the generated test images can be loaded by 
another application (Preview in my case). I'll send the images 
off-line.
