Graphical comparison engine
Capturing some discussion between @sethhillbrand and me.
It would be nice to build a graphical comparison engine that can essentially compare two sets of EDA_ITEMS.
The concept we discussed is a proxy VIEW_ITEM that points to one or two EDA_ITEMs and generates a representation of a comparison between the two. The actual representation can be controlled by some painter properties (maybe you want to only see the intersection, or maybe you want one to be red and the other green, etc)
This can be used for a number of new features:
- Diff tool
- Footprint/symbol updating comparison
- Gerber comparison
- Better MARKERs
