Re: GCPM "float-offset" and centering

Thanks! Likewise, I think the 'gr' unit is brilliant.

I'd argue that it's still about positioning (not centering), but it
also moves the reference point of the floated element.

So, how would you like to set the reference point?

In your example for use case #30, you use the percentage value to
express centering. Do you think this is better? I'm probably ok with
switching to percentages, in which case my example for use case #30
would read:

blockquote {
  float: top left column;
  float-offset: 50% 50% }

The "vertical 50%" value is quite easy to explain: the midpoint of the
float is positioned half-way down the column. Likewise, 0% and 100%
would intuitively make sense -- at least if one knows the definition
of "background-position".

The "horizontal 50%" is harder to get. Hmm.
