[mkgmap-dev] [PATCH v1] - round coordinates when zoomed out

Having filled some gaps with that last little patch, I was wondering why I still had quite a few gaps when zoomed out. Obviously, the coords weren't being rounded to nearest given the zoom level. So, the attached patch does that rounding and, lo and behold, even more gaps have disappeared. Please give it a go, especially for maps that cross the equator/day line where the coords flip signs. Sure to be buggy but it's looking quite promising. BTW - this patch does not contain the last patch but they probably should be used together. Mark
