Adhere to max resolution setting rather than absolute minimum.

We don't have to do the whole simplify thing here, since all points will be on a single line anyway -- maybe this is too big (I'd argue not, since this _is_ what the user asked for, though maybe you could say 'inter'line isn't the same), but _just_ using the 'any points within 5 micron are the same' rule here is not even close to enough to prevent zits.

done as part of CURA-12774 -- plz test carefully, this might change a bunch of things
