I've reported that FlightGear may crash on Macs with nVidia Graphic cards due to likely driver bug in hardware mipmapping in a multi-thread environment. I've already introduced a workaround for this issue on 1.9.0 but it didn't cover all the nVidia drivers.
So I decided to disable hardware mipmapping on all nvidia drivers for avoiding annoying crash report.

First, please read "Who needs to update" below and check if you need to update the framework. If you have never encounter a crash report while running FlightGear, you don't have to install this update. If you need this patch, then follow the instructions below:
