from the authentication manager like the web process does.

[CSS Regions] Implement visual overflow computation for inline elements
https://bugs.webkit.org/show_bug.cgi?id=125291

Reviewed by David Hyatt.

Source/WebCore:

The patch implements visual overflow computation for inline elements per region. The algorithm
uses the container region of each root line box to determine the lines in a region generated by
a RenderInline. The overflow of a RenderInline inside a region is the smallest rectangle that fits
all the line boxes belonging to that region.

The patch also correctly flips for writing mode the overflow of a renderer before clipping with it.
