Autogen texture files after updating P3D?

Hi,

I updated to the latest version of P3D v3. As always when I update an OrbX product or Prepar3D itself, I did a Windiff to make sure I understand which files are changed.

One thing I noticed is that some building texture files got modified:

Now I don't know whether the texture files from the previous version were unmodified or if they were installed by OrbX (since they update some global scenery-related files). Or did LM themselves actually modify these building texture files
