Not a bad idea :-) I’ll see what I can do later on down the track.

FWIW, I’ve been thinking for some time now that I need to start implementing unit tests around 
fragile code I poke. It might not have caught this issue, but I’m going to try to ensure I put 
together unit tests whenever possible. 

My first attempt at doing so is queued into gerrit already, it’s a very simple one where I’ve 
implemented an accessor and mutator on ImplFontMetric and FontMetric, with the aim of deduplicating 
the ImplFontMetric and ImplFontMetricData classes. 

Obviously the test is very basic, but given the fragility of the code I’m working on, and the 
direct impact of changing something inadvertantly, I’m taking a cautious approach!
