39bafa0cf1 add push_new member function which allows modifying 
current features context (useful when datasource schema
is unknown, so we update context as we go along).

c88d7e723d + access feature_kv_iterator directly on mapnik::Feature::begin()/end() 
+ avoid using 'feature' as variable name as mapnik::Feature will be renamed to mapnik::feature
+ revert 'describe' to 'attributes' (original name fits better in this context I think)
+ make attributes a Puython property

ab101401cd + simplify geometry implementation 
+ removed multiple geometry typedefs
+ use geometry_type
+ revert to storing vertices in vector_vertex
  (previous implementation using std::vector was
   fragmenting heap causing performance issues with large geometries)
+ FIXME: hit_test is broken!

17b61d16c4 More progress on #528: Made setting Feature properties with values of type unicode or str possible. I've modified the UnicodeString_from_python_str from_python_converter so it can also convert python unicode objects (not just encocded strs). It was originally commented out so but it seems to work fine on my tests. Is there anything I0ve overlooked? (Artem?) 2010-03-19 13:42:58 +00:00

4483d59797 Revert previous fix for #89 and add a new improved fix that enhances the 
value class to have a proper null type and do comparisions SQL style so
that null is neither equal nor not equal to other things.
