Miscellaneous Changes

• Hydra Viewer improvements:
  
  • The PxrEnvDayLight sunDirection parameter now has a manipulator
  • The Refine Shape and Scale Edges manipulators for PxrRodLightFilter are now available
  • Viewer Manipulators now display annotations
  • Prevented the default Katana light locator from drawing when a light filter is added to a light
  • The PxrPortalLight and PxrDistantLight guides are now distinct from the PxrRectLight and PxrDiskLight representations
  • It is now easier to select lights
  • We now hide the analytic cookie manipulators if the cookieMode is "physical"
  • The width and height controls on the Barn Size manipulator now match line up with the BarnLightFilter visualization
  • The Rod Scale, Cookie Scale, and Barn Scale manipulator handles will now remain orthogonal no matter how the light filter is transformed
• The RenderMan built-in error handlers are now fully supported (prmanGlobalStatements.errorHandler). This has been extended to include a new handler 'abortall' which indicates the render should be terminated on a katana error
• All provided shaders with a ramp UI now allow a dynamic number of knots
• RfK no longer outputs uninitialized values to PxrRamp's colorRamp parameters
• Deleting primvars and primAttributes now updates in Live Render
• RfK no longer adds "origin" and "OriginalWindow" to the display lines. These values are properly computed by prman
• RfK's display option configuration has been adjusted to align with prman's expectations for crop window and overscan

Fixes

• Fixed live render crashes when deleting or renaming a light
• Fixed an error messaged that was displayed when "Tab" was pressed in the Hydra Viewer when a light with no manipulators was selected
• The Scale Edges manipulator for PxrRodLightFilter in the Viewer are now correctly positioned when the scaleWidth, scaleHeight, and scaleDepth parameters are non-default
• Fixed a bug where a parented, shared light filter using the "Light + Light Filter" Coordinate System was not drawn in the Viewer and Hydra Viewer
• Fix a bug that would cause "point" output channels to be emitted with type "int"
• The UI default value for the Visible In Refraction parameter on lights now matches the default in the renderer
• The preset browser tab works again

• Addressed a bug with the preset browser where  exporting light rigs and materials from a parent group failed

• The preset browser now supports array and dynamic array parameters.  Materials that use PxrRamp can now be correctly saved and imported
• The autocrop option on RenderOutputDefine for raw OpenEXR renders now works
