group-collapsing

[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

<?xml version="1.0" encoding="UTF-8"?>

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

One group would be also ok. For groups and text there are much more optimizations possible, e.g. including anti-groups and full transformation resolution.

Yes id love to see support for removing all groups where possible
