605051 - should be allowed to float the root element

Status: NEW

The root element should be allowed to be floated.  For example, in this test:

the root element should be on the right side of the page.

So doing this involves either breaking the dependency of floats on blocks or having a "block" outside the block generated by the root....  Perhaps the CanvasFrame should inherit from nsBlockFrame?

A floating root element can't really do anything interesting, can it?

Nothing can clear it or flow around it. I guess the only thing is that it shrink-wraps its width and then "float:left" gets put against the canvas left edge, and "float:right" gets put against the canvas right edge. Might be easiest to just hack that support directly into CanvasFrame.

I agree with roc. There's no need to make this complicated.
