Problem of display on the 180°E / 180°W

Hello Omar,

I'm currently translating Ricoo's extrations of VR map tiles in vector maps.

I discovered one issue on the 180°E / 180°W limits in the display (I'm currently using VRTool v1.95)
Here is a short exemple:
For exemple, Fidji Islands. When I zoomed on this archipelago, if I zoomed closed to 180°E/W, east side, display do not show anymore Islands on the west side of 180°E/W. If I zoomed closed to 180°E/W, west side, the same appears for the Island est side of 180°E/W.

I found a solution duplicating Islands with continuous Longitude (ie, if Island on Esta side, also coded with west longitude, ie > 180°W).
=> disadvantage: I increase dramatically the weight of file, imagine for Europe/Africa/Asia/Russia for seeing Chukotskiy Peninsula...

Can you have a look on the problem?

And once again, thanks for the great job you did.

Kindly regards
