Hi

regarding these "synchronisation" problems using sleep (whose results 
can sometimes vary depending on setups), couldn't this be handled with 
some new natfeats functions specific to these regression tests ?

For example natfeats 'save screenshot' would save current screen content 
as a png, and you could call it from a fixed hbl position in the 
fullscreen code, which would ensure you always capture a complete screen.

So, the test could be :

 - natfeats "screenshot filename.png"
 - natfeats "print 'fullscreen test complete'"
 - natfeats "quit hatari"

This way, no more sync problem or sleep to adjust, you can even run 
hatari in fast forward mode during the test and it will work.
