This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

We have a fair number of files that have a particular stale version of the MPL
boilerplate. (It was probably originally correct, and then the official
boilerplate changed, and the stale MPL boilerplate continued to propagate via
copypasting from neighboring files into newly-added files.)
This patch updates this stale MPL text (and *only* the MPL text) to the latest
version, which can be found at https://www.mozilla.org/en-US/MPL/headers/ and
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line

nsReflowStatus::IsEmpty() assertions are added after DISPLAY_REFLOW in the
beginning of the Reflow().
A few Reflow() implementations have Reset() calls at the end which are left
in place by this patch (with an explanatory comment added to each). These
ending Reset()s are only needed for cases where a non-splittable frame
passes its own nsReflowStatus to a child's reflow method. Just in case the
child leaves a "not fully complete" value in the nsReflowStatus, the
non-splittable parent frame must clear out the nsReflowStatus before
returning, so that its own parent doesn't then try to split it.

This patch is written by the following script with some manual adjustment to
the comment in nsRubyTextContainerFrame.cpp and nsRubyFrame.cpp, and
nsColumnSetFrame's constructor.
function rename() {
find layout\
-type f\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -r "s/$1/$2/g" "{}" \;
}
rename "nsReflowStatus *([a-zA-Z0-9]*) = NS_FRAME_COMPLETE" "nsReflowStatus \1"
rename "([a-zA-Z0-9.*]*) *= NS_FRAME_COMPLETE;" "\1.Reset();"
rename "([a-zA-Z0-9.*]*) == NS_FRAME_COMPLETE" "\1.IsEmpty()"

Note that nsMathMLContainerFrame and its subclasses are unchanged since
they are not target of fullscreen (and thus no backdrop frame), and they
have an assertion to ensure we really don't pass any unexpected list in.
Known problem:
It would cause infinite loop if there is any line break happens inside
ruby base or annotation, or the width of container is not enough for
the widest pair/span. This might be fixed in bug 1098272.
Important changes:
* Change base class of nsRuby{Base,Text}Frame to nsInlineFrame
* Make ComputeSize of nsRubyFrame and nsRubyBaseContainerFrame behavior like inline frames
Important changes:
* Avoid using GetPrefISize on the ruby texts in
nsRubyBaseContainerFrame::Reflow, since the size it produces might
not match the size produced by Reflow. The old code calls that on
all the ruby texts to determine how big they are, then reflows all
the ruby bases, and then reflows all the ruby texts. The new code
instead processes one pair at a time, and for each pair reflows the
ruby texts and then the ruby base.
* Change the base class of nsRubyTextContainerFrame from nsBlockFrame
to nsContainerFrame, and stop constructing an nsBlockReflowState for
its reflow.
* Move the code for reflowing ruby texts from nsRubyTextContainerFrame
and to nsRubyBaseContainerFrame.
* Fix the regression that ruby text containers contain span are not
reflowed properly. It is the regression introduced in patch 0.
Known regression:
* This patch drops centering ruby base and annotation in pairs. This
should be fixed in bug 1055676 (ruby-align).
To account for spacing between bases or text boxes during reflow, the line
layout which manages the bases updates its inline direction coordinate based on
the preferred inline size for the corresponding text boxes. Next, the base is
reflowed at the correct inline coordinate. Each paired text box is then also
reflowed at the proper inline position determined by (1) the current position of
its corresponding base and (2) its own preferred width.
In computing intrinsic widths, accounting for spacing is less complicated. The
minimum intrinsic width is the width of the widest ruby column, and the
preferred intrinsic width is the sum of all the ruby column widths. Each ruby
column width is the maximum width of its base box and text boxes. These
individual widths are determined using GetPrefISize on the base and text boxes.
Ruby base container frames store a list of pointers to the ruby text container
frames in the segment they denote. This list of pointers is created in the ruby
frame reflow method before calling the reflow method for the ruby base
container. The list exists and is used only during reflow of the main ruby frame
and is cleared before returning from reflow.
