group-collapsing

Created by: JoKalliauer

Running scour for InputOutput.svg.txt does not collapse groups.

scour -i InputOutput.svg.txt -o InputOutput.svg.txt

If I understand --disable-group-collapsing correctly then it should collapse groups by default.

Input=Output

InputOutput.svg.txt

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE svg  PUBLIC '-//W3C//DTD SVG 1.1//EN'  'http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd'>

desired output

whish.svg.txt

Or what does group collapsing mean? (maybe one example)
