Restore trRenderFrame (which used to be in main.cxx before the
split). If SimGear is configured --with-jpeg-factory, then FlightGear will fail to build unless this function is present. FIXME: this is very messy architecturally -- find a better solution, like passing this explicitly as a callback to the libJPEG class (SimGear should not have a dependency on FlightGear).
