Thanks for that. Presumably some of the portability issues are due to 
the difficulty of manipulating bitmaps, hence TLazIntfImage etc.

Looking back through something I wrote in Delphi I see I used 
TCustomForm.GetFormImage. Bug 11292 implies this is in 0.9.26 for Win32 
and GTK2, position with other widget sets uncertain.

I might take a look at this later but since it turns out to be 
non-trivial it would probably be wise if I concentrated on core 
functionality first.
