UI: fix/rework 'align' computing code.

Previoous code would simply epic fail in complex cases mixing horizontal and vertical layouts,
especially 'column-major' ones.

This ones tries to be more generic and robust.

Globally working rather good, but there are still several glitches compared to previous code.

Also, needs to be refactored to be less verbose.

Also, note that it's roughly 50% slower than previous code - but remains acceptable imho.
