When printing, every page has the same origin. So doing this change naively
would result in the first page having all the display items for every page
added to it, and all but the first page's display items being pruned
away by PruneDisplayListForExtraPage. This would making printing long documents
very slow. We avoid that problem with the new check for
NS_FRAME_FORCE_DISPLAY_LIST_DESCEND_INTO, so the only pages other than the
current page we descend into are the ones with placeholders for abs-pos content
on the current page.

We need this to set the initial visible rect during display list construction.
Eventually we'll also be able to get rid of the dirty rect parameter to
nsIFrame::BuildDisplayList.

One nice bit of fallout from this bug is that handling plugin background
readback is simplified. We no longer have to fiddle with display item
visibility calculations; only layer occlusion culling has to know about
readback.

Calling Layer::SetVisibleRegion multiple times in a transaction can result in
unnecessary IPC traffic.
This patch removes Intersect(childGfxBounds). This is only needed to
restrict the visible region to something sane for 3D transforms, and this will
be fixed up in a later patch.

InitCBReflowState() copies the mCBReflowState from the parent
reflow state for table frames, which is null for "dummy" states,
so it would lead to a crash in InitConstraints() which assumes
non-dummy states has a non-null mCBReflowState.
