Harald JOHNSEN:

I have corrected a few bugs with the owner draw gauge, weather radar code and heat-haze effect.

- od_gauge.cxx :
  corrected a rendering bug where the generated texture was only visible
  from a certain angle or distance ;
  corrected the search of textures inside the aircraft scene graph ;

- wxRadar.cxx :
  the echo of clouds was lost when the pilot was not looking in the
  plane direction ;
