• Fixed Diagram.layoutDiagram not performing a layout immediately if called within an ongoing Diagram update (such as during a DiagramEvent like "InitialLayoutCompleted").
• Fixed Panel.itemTemplate so that it is used, not the default item template, when the panel cannot find any template with the given category name in the item data.
• Diagram.viewSize, if set, now takes precedence over the size of the Diagram.div. It is not typical to set both a DIV and the viewSize, but in environments where a DIV is set automatically it may be useful for testing purposes to set an explicit viewSize as well.
