Ting-Yu Lin 40fcd21b9a Bug 1277129 Part 7b - Rename various ReflowState variables to ReflowInput. r=dbaron
This patch is generated by the following script:

function rename() {
find .\
     -type f\
     ! -path "./obj*"\
     ! -path "./.git"\
     ! -path "./.hg"\
     \( -name "*.cpp" -or\
        -name "*.h" \)\
        -exec sed -i -r "s/$1/$2/g" "{}" \;
}

rename "([[:alpha:]]*)([rR])eflowState(s?)" "\1\2eflowInput\3"
