[mkgmap-dev] [Patch v1] improve filters to reduce artifacts in shapes at lower resolutions

Hi Gerd,

a bit off-topic but similar problem.

Could you apply important points to line objects too? Important points 
would be points, where line objects are crossed. I think you already 
find important points for roads on routable map and layer 0. You could 
preserve them on upper layers. And maybe would be possible to find 
important points for other line objects too.

The reason for this is that simplification doesn't preserve line 
crossing. For example T-like crossroad can become 2 separate lines. This 
is mostly invisible, but looks bad when spotted.
