- Add support for displaced thresholds on runways with nonprecision and visual

Browse source 
markings.
- Fix a couple very small alignment/sizing problems.
- Use a different texture (similar to rest) before aim points on nonprecision
  runways.  This will potentially make things easier if we want to add
  skid marks to the textures.
- Fix a couple bugs (el stupido) in precision marking generation.
