Changes between Version 5 and Version 6 of April 2012 MeetingRethinkingRendering

-                      v5
+                      v6
 * (??): perhaps the confusion is over mixing functionality and ownership - there's only one tree, but we split the functionality over multiple classes
   * maybe you could have one tree with different attributes instead of different subtrees (?) - this is a different way to look at the problem but hasn't really been investigated
+  * smfr: you might end up re-creating trees just so you can keep track of what's going on during traversal
+    * (??): maybe they would at least be homogenous trees in that case
+* (??): maybe render layers shouldn't be boxes, because they don't need all of the aspects of a box
