Slightly out of theme. About incremental rendering and flexible layouts.

Let's say we have following markup:

<body>
<p class="header">Header</p>
<div class="content">Some long content</div>
<p class="footer">Footer</p>
</body>

And following styling:

body { height: * } /* takes everything that left in the view
                               from body margin and paddings */

div.content { height: * } /* takes everything that left in the
                                        container (body here) from margin
                                        and paddings and other non-flex
                                        elements (header and footer here) */

There are two scenarios:
1) intrinsic height of div.content is less than space available.
    In this case p.footer will be at the bottom of the view,
   div.content will span all visible area. Content is small
   so not incremntal rendering is required.
2) height of div.content is greater than space available.
    In this case p.footer will be out of the view and no
    computation of flexes is required so long documents
    can be rendered incrementally as it is now.

Markup and styling above can be modelled in
quirks mode as:

<table height=100% width=100%>
<tr><td class="header">Header</td></tr>
<tr><td class="content" height=100%>Some long content</td></tr>
<tr><td class="footer">Footer</td></tr>
</table>

This requires twice more DOM elements and does
not allow incremental rendering.

Yep, this too.
