This is the bulk of the changes. - DisplayItemScrollClip is removed. Instead, we will have 1) ActiveScrolledRoot and 2) DisplayItemClipChain. - ActiveScrolledRoot points to a scroll frame and allows traversing up the scroll frame chain. - DisplayItemClipChain is a linked list of clips, each clip being associated with the ActiveScrolledRoot that moves this clip. - Each display item has an ActiveScrolledRoot and a clip chain. - nsDisplayItem::GetClip returns the item of the clip chain that scrolls with the item's ASR. The separation between "regular clip" and "scroll clips" mostly goes away. - Tracking clips in the display list builder's clip state happens very similarly to how regular clips used to be tracked - there's a clip chain for content descendants and a clip chain for containing block descendants. These clip chains are intersected to create the combined clip chain. - There are strict rules for the ASR of a container item: A container item's ASR should be the innermost ASR which the item has finite clipped bounds with respect to. - At some point in the future, ASRs and AGRs should be reunified, but I haven't done that yet, because I needed to limit the scope of the change.
