[mkgmap-dev] Inter-tile routing now available in trunk

Folks, Robert heroically discovered why the inter-tile routing was not functioning at all well and I believe it's now become quite useful so I have committed the code to the trunk. I appears to work fairly well in mapsource although I have found that for long routes it gives up and draws a straight line even though it can route OK if you add some intervening waypoints. So, more work required but it would be great to get some feedback as to how it's currently performing especially on real gps units. Obviously, if you find this new code has broken the intra-tile routing, it can be backed out. All feedback welcome. Cheers, Mark
