Because - OTF reprojection is mature and stable - Should be no cost when not required - transforms are shortcut when not required - Reduces code complexity - Canvas OTF support was being incorrectly used as a flag for whether measurements should be made in ellipsoidal mode. Instead the project's ellipsoid setting should be checked for this. - Should simplify behavior for new users
