    * Renamed 'PerlinEx' filter to 'Perlin2' for consistency and future-proofing. 
    * Ensured all filter options pages say 'filter options' (not 'properties').
    * Implemented 'stop graph' feature in threaded build.
  * All:
    * Test behaviour when filters fail, or when rendering is cancelled. 
    * Fixed error reporting in filter & graph functions (couldn't show log view from worker thread).

  * Implemented graph load/save in CzGraph.
  * Associate 'zgraph' extension with L3DT in installer, and handled in command line processor.

    * Implement filter picker tree dialog, for nested tree namespaces.
  * In ZeoGraphWnd:
    * Added text overlay on mouse hover over pins, and render their current value.
