This page describes the motivation and design for a refactoring of diagrams, to give them a semantics based on computing fixed points of functions from "context" information to raw tree of primitives together with some summary information.
Reference
See the original "manifesto" and ensuing mailing list discussion here: http://thread.gmane.org/gmane.comp.lang.haskell.diagrams/383
See also later IRC discussion beginning here: http://ircbrowse.net/browse/diagrams?events_page=935
Detailed design
Most of the changes should be in the diagrams-core package, though a few things in diagrams-lib may need to change as well.
diagrams-core
No changes should be necessary to the following modules (all prefixed by Diagrams.Core: Envelope, HasOrigin, Juxtapose, Names, Points, Query, Trace, Transform, V
I'm not sure about Style yet.
