- Muwave icon: remove handles, make serpentine blue, thicken and pixel align
- New, simplified zone and rule area icons
- Simplify draw tools by removing edit handles/guidelines - improves contrast
- Reorder draw tools in toolbar/menubar to make a little more sense
- Rotate measurement icon (ruler) to match bottom left -> top right
This is *a work in progress*, so some features are missing, and/or could be modified.
Mainly keepout zones are not yet exported to autorouters, and pads are not taken in account.
Some code cleanup in polygon.*
