Among the latter, `font-family-013.htm` and `fonts-013.htm` are testing

They were passing because Ahem was not available at all,
and now fail because we don’t implement font fallback correctly.
The others also use Ahem, but I don’t understand yet what’s going on exactly.

at start up or not. This enables both the new behavior (e.g. always
return an image even for broken urls) as also the previous one.
Additionally, this patch cleans up some miscellaneous formatting issues
and refactors files in `layout/css/` somewhat to eliminate needless
levels of indirection. It also fixes our handling of presentational
hints that only apply if border is nonzero.
matching, and use it for `<input size>` and `<td width>`.
This implements a general framework for legacy presentational attributes
to the DOM and style calculation, so that adding more of them later will
be straightforward.
