* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly) * zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple * osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf) * SlideShowConstructor: enable/disable CoreVideo via a environment variable (P3D_ENABLE_CORE_VIDEO) * RestHttp: mouse-motion-events get interpolated * RestHttp: unhandled http-requests get sent as an user-event to the event-queue, all arguments get attached as user-values to the event * modified some CMakeModules to work correctly when compiling for IOS * fixed a compile-error for IOS in GraphicsWindowIOS * some minor bugfixes"
