This may be similar to my own thoughts...

My idea is that we need not a very high internal resolution in pcb.

Important may be the correct mapping of user input to internal pcb
coordinates.

Example:
You have a finished pcb board, which an engineer has made with mm units
in mind. You want to rebuild it, so you measure all dimensions of traces
and elements with a tool with mil units.

You end with a couple of mil coodinates -- derivation should be at least
one unit of your measurement tool, i.e. 0.01 mil for our pcb program.
Should be OK.

I have to think about this more...


Best regards
