 * Additional frame-state bits used by nsBlockFrame

 *
 * NS_BLOCK_CLIP_PAGINATED_OVERFLOW is only set in paginated prescontexts, on
 *  blocks which were forced to not have scrollframes but still need to clip
 *  the display of their kids.
 *
 * NS_BLOCK_HAS_FIRST_LETTER_STYLE means that the block has first-letter style,
 *  even if it has no actual first-letter frame among its descendants.
 *
 * NS_BLOCK_HAS_FIRST_LETTER_CHILD means that there is an inflow first-letter
 *  frame among the block's descendants. If there is a floating first-letter
 *  frame, or the block has first-letter style but has no first letter, this
 *  bit is not set. This bit is set on the first continuation only.
