Thanks Kristian.  I found out later that the other mailing list is for questions relating to GTK+ version 1.  
It seems as if version 1 is still being developed alongside version 2 but I'm not sure why.

Anyway, I've managed to find out that under OS-X, hardware acceleration is only available for certain 
supported chipsets, which seems reasonable enough - but even when it's supported, only 3D acceleration is 
enabled by default.  Bizarrely, 2D acceleration is disabled by default and needs to be enabled using 
something called that Quartz Debug Application.  The worrying thing is that this probably makes sense to 
someone at Apple....  :-(
