OK, now that is at least the type of definitive statement I've been
looking for. (I have recently opened a discussion with DTS on some
of these
issues.) So apparently, there are some things internal that change
when you
call "setLayer" besides just the layer?
I can't speak to the specifics, I've not investigated if fully.
I have also figured out (and had confirmed in the archives) that
if you
want to use layers in a scrollable view, the scroll view (or at
least the
clip view) better be layer backed. But that implies that the
scrollable
view will also automatically be layer backed. Apparently, that
changes when
you do "setView" on it that makes it layer-hosting?
if a view in a view hierarchy is configured as layer-backed, all
subviews are (this is currently only documented in the Animation
Overview, Hybrid Apps section... this will be fixed shortly.
Then that raises the question of what happens to the view's layer
when
you change the frame of the main (scrollable) view? Does it
automatically
resize? Or should you programatically resize the layer? Or just
replace it
using setView again to set it's frame to the new view frame size?
haven't investigated this either.
