/*! \page changelog Changelog

- <b>OpenFlipper 1.4 ( ?? , 15246 )</b>
     - <b>Significant interface changes and Bugfixes</b>
         - Interface: Don't use allow addEmpty in FileInterface anymore (deprecated long time ago and basically unused! The type plugins handle this signal anyway.)
         - Interface: Renamed and extended functions to block scenegraph updates. OpenFlipper::Options::loadingSettings replaced by 
             - sceneGraphUpdatesBlocked()
             - blockSceneGraphUpdates()
             - unblockSceneGraphUpdates()
         - Bugfix: Fixed undirected shooting function returning wrong nearest triangle (was always the one with the most negative distance)
         - Interface: RayCollision is now a sorted vector conbining standard pairs of the hit handles and their distance to the hit
     - <b>ACG</b>
         - General
             - Added simple scenegraph analysis function to get bounding box and multipass number
         - Geometry/BSP
             - Removed dependency from bsp to OpenFlipper (not required and causes unnecessary linking)
             - Added directional BSP ray shooting including unit tests
             - Fixed undirected shooting function returning wrong nearest triangle (was always the one with the most negative distance)
             - Interface: RayCollision is now a sorted vector combining standard pairs of the hit handles and their distance to the hit              
         - Unittests
             - Unittests for BSP
             - Unittests for algorithms
     - <b>Core</b>
         - Speedup getObject in Pluginfunctions, as most functions used the slow recursive version instead of the std map accelerated version in PluginFunctions   
         - Speedup: Modified the resetScenegraph stuff which ran the bounding box and multipass actions too often (Approx. factor 4 speedup in this function)
         - Speedup: Block updates wile loading files from the command line
         - Speedup: Reset drawmodes only when not locked
         - Speedup: Don't send view updates to plugin, if scenegraph updates are locked
         - Speedup: Removed unnecessary update function from resetSceneGraph (already updated on demand)
         - Speedup: Removed redundant call in BaseObjects next function
         - PerObjectData
             - Added set of standard per object datas
     - <b>Interfaces</b>
         - RPC Interface
             - Support for rpc calls with return value and up to 6 parameters
     - <b>ObjectTypes</b>
         - General
             - Speedup: Removed the get_unique_name functions when adding any object, as this would cause linear time when adding new objects.

             - Added draw mode for colored vertices
     - <b>Plugins</b>
         - Datacontrol
             - Added context menu item to copy material to targeted objects.
             - Speedup: Accellerate Treeitem lookup for child by a map. This should speedup large object count handling significantly.
             - Speedup: Remove duplicate function calls
             - Speedup: Only handle lightsources in file opened, if they are added
         - File Bundler

         - Skeletal Animation
             - Speedup Skeletal Animation Plugin by only caching skeletons.
         - Type Splat Cloud
             - Name group after splatcloud
     - <b>Scripting</b>
         - Core: Added getToolbox method to scripting interface.
         - Core: Added scipting functions to block and unblock the scenegraph (speedup while handling large object counts)
     - <b>Documentation</b>
         - Removed example path from doxyfiles for user documentation

- <b>OpenFlipper 1.0 RC6 ( 2010/03/17 , 8742 )</b>
     - <b>Core</b>
         - Splitted File Plugins ( Now there are type plugins loaded first to register types and the file plugins to load data)

         - Changed handling of ObjectSelectionChanged
         - Updated internal types handling (directly initialized by core now) 
         - Handle object tree integration for BaseObjects automatically (No longer necessary to call the setParent Function)
         - selectionChanged, visibilityChanged and objectPropertiesChanged are now handled internally. If One of these changes, the signals
               will be emitted by the core and passed to the plugins.

         - Implemented drag and drop for files to OpenFlipper
