Added the ability to specify Metadata overrides to specify instances of Plugs and Nodes.
Added UI Editor. This allows the user plug layout for any node to be edited - plugs can be reordered, dividers added and help strings specified. In particular this allows the creation of custom UIs for Boxes, which can then be exported and loaded by References.
Fixed initial unsortedness of PathListingWidgets.
Added PrimitiveVariables node. This allows arbitrary primitive variables with constant interpolation to be added to objects.
Added Duplicate node. This allows arbitrary numbers of duplicates of subhierarchies to be created, each with their own transform.
Specifying lockgeom=1 by default for all OSL shading engines. This means that primitive variables (user data in OSL parlance) are not automatically mapped to shader inputs unless those inputs have explicitly set lockgeom=0 in the source (which is rare). This almost doubles the speed of a simple image noising operation.
Fixed OSLShader::acceptsInput( NULL ) crash.
Added PlugLayout class, which creates node editor UIs driven by Metadata. This will replace all existing plug layouts over time.
Added StringAlgo.h, containing various string utilities, including wildcard matching (#707).
Added metadata accessors to OSLShader.
Fixed module import order and namespace pollution issues.
Replaced Metadata regexes with new string matching code.
Added Metadata signals emitted on registration of values.
Made NameWidget accept None for the the GraphComponent.
Added borderWidth argument to SplitContainer constructor.
Added PathListingWidget setHeaderVisible()/getHeaderVisible() methods.
Added PathListingWidget.pathAt() method.
Fixed bug in GafferUI::Pointer::setFromFile( “” )
Added a DictPath.dict() accessor.
Moved NodeEditor.acquire() to NodeSetEditor.acquire(). This allows it to be used to acquire an editor of any type.
Added fallbackResult to WeakMethod.
Fixed CompoundPlug plugSetSignal() emission when children change.
