My patch certainly doesn't meet any definitions or format. I have no 
time right now to rewrite the patch correctly and according to the 
coding standards. If you wish that I send you another patch with the old 
code replaced, tell me so and I will. However it will be of the same 
(low) quality, which I think is not ready to replace the current code.

Did anyone actually tried it to see the speed improvement? I have done 
no benchmarks but what I described in an earlier email (how to plot big 
SRTM files) now works *much* faster (*10 or more speed improvement).

For now I will be happy to see an entry in the TODO file about 
optimizing the highly innefficient "matrix" parser. In the future, if 
you haven't found the time to fix it, perhaps I will submit a proper 
patch, compliant to the coding standards and good enough for you to use it.

Thanks,
Dimitris
