      Yet another optimisation for the gaussian filter. This adds a compile · d08ba168

      time option to use floats instead of integers. Performance comparison
      is:
      (performance is in numbers of samples output by oprofile. Less is better)
      
      sigma   old version (integers)       integers       floats
       2.0    556889                    466435 (-17%)  481293 (-13%)
       4.0    902749 (core maxed out)   732755 (-19%)  716070 (-21%)
      
      I'll have to check why relative performance gain depends on sigma when
      comparing the the float and integer versions.
      
      I'll aslo add another module (most likely named fastgaussianblur.c)
      based on Frederick M. Waltz and John W. V. Miller's "An efficient
      algorithm for Gaussian blur using finite-state machines" article. This
      seems to be way faster (but it's doesn't allow as much granularity in
      the gaussian's choice and it adds an error compared to this module).

      The arm.config error that occurs is just that someone commited a dos file...
      dos2unix could fix it. but it is not on Apples....
