NodeGraph now only drag-selects nodes that are wholly contained in the drag area, not merely intersecting it.
Added a Backdrop node (#153).
Added support for “help” shader annotation in RenderManShaderUI (#536). This provides help for the shader as a whole and is mapped into the MetaData as the node description, appearing in the NodeEditor as a tooltip.
Added optional continuous update to string PlugValueWidgets, controlled by the continuousUpdate parameters to the constructor. This transfers the text from the ui to the plug on every keypress.
Fixed serialisation of dynamic BoxPlugs.
Improvements too numerous to mention.
