So what if a road heads north-west (diagonal), is it straight on a
Mercator projection or on a linear lat-lon grid?
If a straight road in Ontario goes from (51, -86) to (53, -88),
does it pass through (52, -87) or not? If it does, that's a
straight line in a linear lat-lon grid, but it is a curve in a
map using Mercator's projection.
