/**
|
|
* Additional frame-state bits used by nsBlockFrame
|
|
* See the meanings at http://www.mozilla.org/newlayout/doc/block-and-line.html
|
|
*
|
|
* 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.
|
|
*
|
|
* NS_BLOCK_FRAME_HAS_OUTSIDE_BULLET and NS_BLOCK_FRAME_HAS_INSIDE_BULLET
|
|
* means the block has an associated bullet frame, they are mutually exclusive.
