I'd like to see that as well - but am still not quite sure, if it would
be feasible to let TYPO3 calculate % values. I doubt that it could be as
simple as calculating em or ex values...

Well. This doesn't sound that simple for me regarding to easy
configuration via TS and/or algortihmic handling... and I doubt the idea
is ready for this list - so there's at least one more thread at dev-list
- thanks for pointing to.

Finally my point then would be - hoping to get some feedback from this
list ;) :

I think, what could be made ready for the core right now without
something that at least I for myself would have the time for before long
is a feature that

- allows flexibility in units (em/ex/whatsoever) when rendering images

- doing some simple linear scaling for the dimensions if this is
eventually wanted

- possibility to omit dimension parameters completely for some layout
that would have to be styled in own css definitions (e.g. for realizing
some percentage-based layout).

I prefer the usage of % as well.
Though I wouldn't say some at least scalable concept doesn't has
anything good ;)
