- TODO: look at padding?

- Look ahead here for kern and raise.

- (cols "foo" ((raise . 1) "bar"))
- (cols "foo" ((bold (raise . 1)) "bar"))
-
- When constructing the molecule for bar, all normal extra
- properties found, such as bold, are used for the construction
- of bar's molecule. But for kern or raise, it seems that we're
- too late then, translating bar's molecule has no effect (or
- maybe the effect of translating gets nullified when bar's
- molecule is `added_to_edge' of the molecule for foo?)
-
- So, while constructing foo's molecule, we look ahead for the
- raise of bar. The HEAD of the description of bar may be a
- single property, or a list, so we must check that too.
