Last change on this file since 7861 was 7860, checked in by landauf, 14 years ago

fixed a few issues related to the free mouse look mode (default CTRL key):

  • cursor is now moved to the center of the screen after leaving the mouse look mode
  • spaceship doesn't spin anymore after leaving the mode
  • camera doesn't drag back to the original position after leaving the mode, but jumps back immediately
  • Property svn:eol-style set to native
