Gaffer 0.35.5.0-arnold5

Features

• Added a new dispatch application (#2601).
  • This app dispatches task nodes such as ImageWriters, SystemCommands and Render nodes,
    either from within an existing .gfr file or by creating a script on the fly. This differs from the execute
    app in that it performs a full dispatch via a dispatcher, rather than executing a single task node.
  • The gui mode of this app uses a more general DispatchDialogue which can be used by external
    tools for customized dispatching.

Improvements

• Arnold Renderer : Improved performance when outputting shaders (#2595).

• PlugLayout : Added support for embedded PlugLayouts (#2596).
• Application : Run startup files before evaluating args (#2601).

• BoolPlugValueWidget : Fixed displayMode metadata handling. This restores the little
  switches on the Attributes nodes (#2553).

API

• Metadata : Improved wildcard matching (#2536) :
  • Stopped '' matching '.' in a plug path. This mimics how '' doesn't match '/' in a
    glob match or in the PathMatcher.

    PathMatcher does.
• ImageAlgo (#2561) :
  • Added support for lambdas in parallelGatherTiles().

    that once activated, the CameraTool will remain active even after another tool has
    been chosen.
