- initial way labeling

- add no-projection option for mapdata
- use depth buffer for line clipping to tile - no more scissor, yay!
- extract line and poly render function from maprenderer
- use one vbo for both polys and lines
- use linear interpolator for fling-scroller
- add 'exclusive' negative matcher to rendertheme
- add some more options to rendertheme, kind of inheritance at least for
  lines, see theme
- add caching for node tags -> renderinstructions
- ...
