The previous code assumed all font sizes were in px, but now we perform
the conversion. There is an existing bug with em sizes returning 0,
which seems to affect other places too - see
`NodeWithStyle::apply_style()`.
This also implements 'larger', 'smaller' and calc() font-sizes.
This patch spreads box-shadows around:
- The Values important to box-shadows are stored in a BoxShadowData
struct
- StyleProperties knows how to construct such a struct from a
BoxShadowStyleValue and a Node knows how to ask for it
- CalculatedValues contain BoxShadowData and expose them
Try to find a font that has at least some of the requested properties.
This makes e.g. rfcs on tools.ietf.org easier to read since their
headers are now bold.

The background-repeat value may be specified as either one- or two-value
identifiers (to be interpreted as horizontal and vertical repeat). This
adds two pseudo-properties, background-repeat-x and background-repeat-y,
to handle this. One-value identifiers are mapped to two-value in
accordance with the spec.
