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...
