a7e7b4c21d Cleanup options. 
Also omit short option strings of advanced options for now (if we offer them again in future, they should be chosen very carefully as should the options for which we offer them)

7cb0d36d72 Improve precision options for smaller output size (#131) 
Add a separate precision option for curve control points (--set-c-precision)
This can considerably reduce file size with marginal effect on visual appearance.

01cb120d71 Reduce precision of lengths in viewBox 
This fixes #127.
Also simplify splitting of viewBox lengths and avoiding a "FutureWarning: split() requires a non-empty pattern match" at the same time

f5a61eeeb3 Even better fix for 8f87118725 
(previous solution still did not work for numbers like 123.4 with precision < 3)

8f87118725 Only use number representation with reduced precision if it is shorter than the initial representation. 
Before it could happen that "123" was replaced with "1e3" if precision was set to 1 which is obviously not desirable.

b00b374e64 Fix generation of non-scientific number representation. 
Before numbers often were already in scientific notation due to the str() implementation of Decimal leading to strange optimization results.

2487f4433b Fixes to globals used for tracking statistics (#118) 
- Collect globals in `scourString()` and make sure they're all properly initialized to zero. Before statistics were wrong when scouring multiple files/strings because initialization was only done once when loading the module.
- harmonize names
- adjust according to PEP 8 while at it (including leading underscore to mark as non-public)
- include one missing variable in statistics output (number of comments removed)

1aa5722c6a Fix conversion of cubic Bézier "curveto" commands into "shorthand/smooth curveto" commands. (#110) 
When the preceeding path segment is a Bézier curve, too, the first control point of the shorthand defaults to the mirrored version of the second control point of this preceeding path segment. Scour always assumed (0,0) as the control point in this case which could result in modified path data (e.g. #91).

29e005bf7b Improve handling of scientific vs. non-scientific notation 
* Negative exponents were not handled in a reasonable way (e.g. 0.000001 remained unchanged)
* Trailing zeroes were not always properly removed

9e4b9d6f5e Improve behaviour of numerial precision reduction 
* Previously all calculations were immediately done with the precision specified by the user, resulting in accumulation of numerical errors and in some cases very discernible abberations from the initial image (e.g. #80)
* Now all calculations are done with default precision (the module "decimal" uses a whopping 28 signifigant digits initially!) and only at the very end coordinates are rounded to the desired precision.

842123a393 Fix improper comparison of numeric default attribute values with textvalues resulting in wrongly removed attributes (#101) 
For example for `orient="auto"` SVGLength() returns (value=0, units=Unit.INVALID); since the default value for `orient` is zero it was removed as there was check for a valid unit.
