Sorry to pick up such old message, but does "visibility:hidden"
indicate doing layout/reflow only while not rendering on the screen,
if we divide the process into these 3 steps -
* frame construction (building the tree of objects)
* reflow (determining their positions; should perhaps have been
called Layout instead), and
* painting (drawing them on the screen) (the code to determine
targets for events is closely connected to the painting code, so it
can be considered part of this area).
Thanks.
