Exchenges defines with static const.
Implements FileVideo.
Fixes Comments in FileVideo.
Ugly commit because I need access to this stuff from bulgaria. Works on the YUVDataVideo.
Fixes a big bunch of ugly issues which made everything uncompilable or unrunnable. But beware, the fixes mostly are just removal of the faulty code (as in the restore method of the video scrubber, because the getPointer methods in the memento could be broken beyond repair (still, i repaired as much as i could) or in the histogram tests due to unhandled OGLExceptions)
Removes the faulty and probably unnecessary invalidConstruction testcase from the videoscrubber testcases.
Merge branch 'Jonas' + memento interface change fixing template cast issue for all classes but saveablelist
