Speculating successfully about svgz compression is usually hard, by the
way; in real tests it can turn out that normalizing a file that uses
both -90 and 270 interchangeably results in a more common keyword match,
whether we normalize both to -90 or 270, as long as we normalize them at
all – so try using a repository of real-world data for crunching out
aggregate gains and losses using different algorithms if you're
interested in good data on compression effects.

I've experienced enough peculiarities with gzip not to speculate too
hard on what effect changes on input data will have on output data from
gzip – like a large web page with inline normal javascript compressing
to less than the same page with minified javascript, after gzipping
both.

(So if we ever try doing something like a special mode for producing
optimally small svgz files, a gz whiz should probably look into the
optimal kind and location of redundant data to inject to make the gzip
dictionaries favourable for reducing end size, which is yet again
another radically different problem to tackle. :)
