   As you can see, update_dither and print_color have been succesfully
   inlined and more important the runtime is MUCH better.  
   However, the performance gain is smaller if you run code without debug
   and profiling information.  The gain is about 30%.  But I think this is
   substantial enough to put the change into the repository (Robert?).

If the gain is substantial when compiling optimized then it's worth
doing.  Don't trust any gains made with anything not compiled with the
appropriate -O flag.

BTW, you might also want to try compiling -O6 -funroll-loops or some
other options.

   Nevertheless I think the code would speed up a lot if all functions that
   are called for every dot are inlined.

That's probably true.
