We (Antenna House) implemented the line grid feature and the block-snap
property (with name '-ah-baseline-block-snap'). See:
http://antennahouse.com/CSSInfo/extension.html#axf.baseline-block-snap

Value: none | [auto | before | after | center] || [border-box | margin-box]

'auto' is same as 'before' on top of column, same as 'after' at bottom 
of column, otherwise 'center'.

[border-box | margin-box] specifies the edge used to align the block on 
the line grid. 'border-box' is the default.


While we tried to implement the css-line-grid with simplified syntax 
and feature, Håkon also wrote similar proposal in his CSS Books draft.
Håkon and I had a discusion about this and now his proposal and what we 
implemented are similar.
I'd like to support css-line-grid when the spec will be finished.
