Gaffer 0.43.0.0

Features

• GafferVDB : Added PointsGridToPoints node and visualisation
  of VDB point grids (#2386).

Improvements

• Appleseed : Added support for Capsules generated by the Encapsulate
  node (#2402).
• ImageReader (#2380) :
  • Reimplemented to use Gaffer's native cache instead of
    OpenImageIO's cache, giving speedups of 20-30% in some cases. This
    also paves the way for introducing deep images to Gaffer.
  • Added initial support for multi-part OpenEXR files.

Fixes

• ValuePlug : Fixed problems when serialising compound plugs (#1500, #2395).
  • BoxPlugs were being serialised with setValue() calls for the leaf plugs
    and the top level plug itself.
  • FormatPlugs were incorrectly attempting to serialise a getValue() call
    at the top level even when input connections existed at the leaf level.
    This prevented a common pattern for the dispatch of image networks from
    working.
• Camera node : Fixed "Copy From Viewer" tool menu item (#2396).
• SceneInspector : Fixed transform component display (#2396).
• Expression : Fixed bug caused by non-serialisable input plugs (#2395).
• CollectImages/Merge/Offset : Fix out of bounds input tile accesses
  (#2380).
• TabbedContainer : Fixed an incompatibility with Qt5 (#2426).
• PythonCommand : Exposed imath module to the execution command (#2428).
• CompoundPlug : Added compatibility config for legacy gfr files (#2429)..
