comparison engine/core/model/metamodel/timeprovider.h @ 181:56ac89189bc4
fixed time handling in fife:
- the time scaling method was unreliable when changing the time factors (jumping in the moment of the change)
- replaced much calls to SDL_GetTicks with TimerManager::instance()->getTime()
- some other time related cleanup
