This is where we could implement part of ruby-align

Doesn't work with all-latin text, where expansion opportunities are not inserted at the end of every run.

Seems like with some cleanup, this could could move inside FontCascade::expansionOpportunityCount? Maybe I am not understanding the code completely though.

> +        if (run.forcesLeadingExpansion() && !m_afterExpansion && !FontCascade::initialExpansionOpportunity(m_run.text(), m_run.ltr() ? LTR : RTL))

Same here. You had to repeat the same code. If you could shift this into FontCascade::expansionOpportunityCount, you could avoid duplicating code.

> Source/WebCore/rendering/RenderBlockLineLayout.cpp:740
> +                if (textBox.forceLeadingExpansion() && !FontCascade::initialExpansionOpportunity(renderText.stringView(), run->box()->direction()))

> +                if (textBox.forceTrailingExpansion() && !isAfterExpansion)
> +                    ++opportunitiesInRun;

Why don't you need the forbidsTrailingExpansion() case that removes an opportunity that you had in the other code that was just after FontCascade::expansionOpporunityCount?

>              if (is<RenderRubyRun>(run->renderer()) && textAlign == JUSTIFY && run != trailingSpaceRun && downcast<RenderRubyRun>(run->renderer()).rubyBase()) {

Seems like this code has gotten substantial enough to warrant its own helper function.

These are tests are failing on Windows. Please add a skip (if relevant), or roll the patch out.

[Brent Fulgham]

Actually, these tests are failing on EFL, GTK, and Windows. Do these changes rely on something Mac-specific?
