AFAIK typically all modern browsers' HTML engines (Mozilla's Gecko, WebKit,
Opera's internal one) do their own layout as no system provided text
renderer will render the text as it's required by www-standards today
(different languages with glyph composition, left<->right direction, CSS
v1, 2, 3... etc).  Also because they need to be portable.

But typically text rendering is one of the main bottlenecks in Browser
speed.  And with all the extra information attached to the text, in memory
it can take hugely more than the rendered html file itself, even if
the HTML would contain just text...
