Bug 1277129 Part 5b - Rename nsHTMLReflowMetrics.h/cpp to ReflowOutput.h/cpp and fix #includes. r=dbaron The modification to nsAbsoluteContainingBlock.h and nsBlockFrame.cpp are needed to fix the build error due to the file order changed in the unified build. The #includes are fixed by the following script: function rename() { find .\ -type f\ ! -path "./obj*"\ ! -path "./.git"\ ! -path "./.hg"\ \( -name "*.cpp" -or\ -name "*.h" \)\ -exec sed -i -e "s/$1/$2/g" "{}" \; } rename "nsHTMLReflowMetrics\.h" "mozilla\/ReflowOutput\.h" MozReview-Commit-ID: KWvcG3UtKNn
