Description
To enable deletion of some java code and a somewhat slow step in icon svg processing provide an optional optimized svg path that does the following if/when it produces a shorter string:
- Use relative vs absolute coords
- Collapse repeated lines (e.g. h20 h30 -> h50)
- Use lineto shorthands (e.g. horizontal or vertical line)
- Remove nop instructions, e.g.
l0,0but more generally any command that doesn't move the pen - Decrease accuracy of floats
- Convert degenerate curves to lines
- Drop leading 0 when possible (e.g 0.5 => .5)
- Drop separator between coords when second is negative, e.g. emit
160-160not160,-160 - Use "smooth" cubic/quadratic curve commands when possible (reflection of end of previous gives first control)
That is, implement most optimizations from https://github.com/svg/svgo/blob/main/plugins/convertPathData.js but apply during generation of a String for a BezPath instead of as a standalone step. Consider not implementing arc conversion; arcs have a way of breaking things.
Impact: should cut minutes off the time to produce a complete set of icons.

- Note that as we generate the svg many remove element steps are avoided by simply not generating them
