Cinelerra's batch mode, and statistics it prints at user session end.

After a batch run, the following is now printed on the startup Cin window:

** rendered 4606 frames in 11.699 secs, 393.709 fps

May be if GG adds printing fps after batch file (with provided project xml,

to PTS - Phoronix Test Suite.

Phoronix is one of the interesting websites that GG frequently looks into.
