[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [59791] trunk/blender/source/blender/ editors/space_view3d/view3d_fly.c: tweaks to fly mode

[Daniel Salazar - 3Developer.com]

[Bastard ZanQdo] Does anyone use flight mode? Users have asked numerous
times for simple *FPS style navigation* and not this weird momentum driven,
uncontrollable.. thing. [/Bastard ZanQdo]
