- Rename city_pos_to_canvas_pos as city_to_canvas_pos;
  canvas_pos_to_city_pos as canvas_to_city_pos.
- Both functions return boolean success values; callers check these.
- The parameters are reordered so that the "return" values are first.
- canvas_to_city_pos has its parameters renamed to be more clear.

Issued as PR#4729.
