[murraystevenson]

Improvements

• RenderMan : Added support for spline parameters (ramps).
• OSLShader :
  • Improved loading of spline parameters with additional duplicate endpoints.
  • Added support for loading splines from RenderMan shaders.
• Viewer :
  • Moved purpose menu items from the Drawing Mode menu to the Expansion menu, and renamed the Expansion menu to Visibility.
  • Added purpose presets for Render (Default + Render purposes), Preview (Default + Proxy) and Preview with Guides (Default + Proxy + Guide).
• Render : Optimised attribute substitution when it is not required by all shaders in a shader network.

Fixes

• NodeEditor :
  • Fixed visual bug whereby numeric values could temporarily appear to exceed their min/max range, particularly when using virtual sliders.
  • Fixed unnecessary updates when editing a plug value.
  • Fixed bug adding rows to VectorData plugs - the newly added rows were being deselected immediately after they appeared.
• SceneWriter : Fixed identifiers used when writing RenderMan shaders.
• SceneInspector :
  • Fixed handling of nested UsdShadeNodeGraphs loaded from USD files.
  • Fixed Context has no variable named "scene:path" error when "Isolate Differences" is on.
• ShaderQuery, ShaderTweaks : Fixed handling of nested UsdShadeNodeGraphs loaded from USD files.
• VectorDataWidget : Fixed errors showing popup colour choosers.
• Startup : Fixed UnicodeDecodeError when running in non-UTF8 locales.
• Viewer : Fixed diagnostic shading modes for Arnold's diffuse and specular visibility attributes.
• Scene Editors :
  • Fixed undo after creating a new edit in an EditScope.
  • Fixed "Inspect..." menu item when a property's source can not be determined.
• RenderPasses : Fixed drawing of custom widgets registered by registerRenderPassNameWidget().
• Environment : Gaffer's LD_PRELOAD overrides are no longer inherited by subprocesses launched from Gaffer.
• CustomAttributes, CustomOptions : Fixed inconsistent layout sections.
• Arnold : Fixed inconsistent part ordering in multipart EXR outputs.
• Render : Fixed translation of string substitutions escaped with backslashes (e.g. "\attr:user:texturePath\\").

API

• PopupWindow : Added showWarning() class method.
• Metadata : The registerValues() function now accepts dictionaries containing target metadata. This should be preferred to the previous list-based registrations.
