One PIP area is black in driver's seat

This seems to be caused by having one too many PIP thingamajigs for the engine to cope with. ArmA seems to pick one at random to turn off.

I disabled the bottom left and right hand mirrors as they seemed to be the least useful, to guarantee that the other PIP areas always showed up:

	        class RenderTargets {
            delete LHMirror_dn;
            delete RHMirror_dn;
        };
	

This just makes them appear black, however. A nicer fix would make them use the psuedo-mirror texture that, e.g, the passenger gets, but that's currently beyond my expertise
