mapnik/src/shield_symbolizer.cpp
vspader 9fe4a94c98 Added minimum_distance property to text symbolizers. This prevents the same label from appearing within N pixels (across features).
Shield symbolizer is now a subclass of text symbolizer.
Some small improvements to text rendering.
Fixed up placement finder for horizontal placement.
Cleaned up placement finder.
