Add new find_point_placements to cover the gap left.
Change shield symbolizer to use find_point_placements.
Results are the same as before, but with much less duplicate code.
Slightly changes the result of max_char_angle_delta as now character angles aren't strict against the line angles.
Example screenshots on mailing list! :)
Spacing and no spacing line rendering are done by the same function.
Code is cleaner, performance should be equal or improved.
Text displacement is "Different", better in some cases and worse in others, I can revert it if wanted.
Old non spacing code is not yet removed as it is used by ShieldSymbolizer which I haven't investigated yet.
Individual character placement still has issues, that is my next task to fix!
2. PostGIS plug-in - optional 'multiple_geometries' parameter to control how Multi* geometries built.
3. MarkersSymbolizer (work in progress) to render vector shapes (markers) alonh a path with collision detection.
- libxml2 support
- strict error handling while parsing XML map files
- implemented save_map()
- removed some duplicate defaults
- all symbolizers with icons share a common base class now
(FIXME : label_spacing is still, too slow!!)
2. Re-use some agg objects.
3. placement_finder cleanups!
4. Added support for 'building_symbolizer' - extruded polygons
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.
fixed 'for' loops to work correctly when geom->num_points() < 2
always use prefix increment even for built-in types (good practice!)
e.g ++i
2. agg_renderer.cpp
check for number points in geometries when
applying text/shield_symbolizer.
angle changes too much between characters it finds an alternate
placement), this is specified in the max_char_angle_delta property in
radians (feel free to change it to degrees).
It also improves the text placement around corners trying to minimise
the distance between the center of the character and the line on each
side. This is the major portion of the patch.
