ISSUE-126: Chaining regions

Chaining regions

CSS3 Template Layout
Raised by:
Bert Bos
Opened on:
It could, under certain conditions, be possible to support complex shapes for slots, by creating multiple simple slots and describing in which order they are filled, e.g.:

"a . b"
". . ."
"c . d";
chains: a b c d;

This would create one chain, consisting of the four simple slots in the given order.

However, if the slots of a chain have a size that depends on their content, determining that size becomes an optimization problem, which might require multiple passes. (It's not a problem if all slots have an "outside-in" size, or if only the last slot in a chain has a size that depends on its content. Or at least it's not a new problem: The algorithm in that case is the same as for pagination.)
