Scour should only change precision if -p is given

[Johan Sundström]

Currenly, Scour by default drops precision to five digits, so a file using 7 digits of precision (not all uncommon for Adobe Illustrator files, especially dumb ones, where the whole image is in a view box somewhere 7200 units away from the coordinate system origin) will silently be degraded, without warning.

At least I would not expect lossy behaviour by default; it's non-unix:y.

Along the same lines, it might be good to break up "Number of bytes saved in path data: X" into "Number of bytes saved in path optimization: Y" and "Number of bytes saved in reduced path precision: Z", while at it, as the current number X is a mix of good and maybe-bad trimming.

[Johan Sundström (ecmanaut)]

Submitting a test case that gets severely munged by the precision loss.

Fixed in scour 0.35 [1]
