* Add Sys_GLimpInit for platform specific GLimp initialisation
* Move Unix specific signal handlers to Sys_PlatformInit * (Windows only) Don't set the SDL video driver if SDL_VIDEODRIVER is already set externally * (Windows only) Use the "windib" SDL video driver if in_mouse is set to -1 git-svn-id: svn://svn.icculus.org/quake3/trunk@1440 edf5b092-35ff-0310-97b2-ce42778d08ea
