Restore trRenderFrame (which used to be in main.cxx before the

Browse source 
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).
