In my first attempts at porting Amulet last year (and in
my current attemps also BTW), I used raw memory-visual
for the backing store of windows.
By default, Amulet applications uses windows double-buffering
on all windows - and the copying overhead was not noticeable
on such heavy-weight applications. (The CPU workload
was noticeable however - but this should go away with
hardware accelerator, so...)
Of course, however, rendering speed was not at all a
concern in a GUI library... :-) But globally, Andreas
appreciation seems very accurate (as usual...;-).
