1) Don't plot all footprint texts for each footprint graphic item. 2) Enforce min web thickness around board shapes and board text. 3) Enforce min web thickness around footprint shapes 4) Correctly handle multi-layer zones. (1) and (4) will get cherry-picked back to 6.0, so after rebasing won't actually appear in this changelist anymore....

* with Min Thickness/2, and merges the result.

* Drawback: pads attributes are lost (annoying in Gerber)

* the new algo:
|

* create initial polygons for every shape (pad or polygon),

|
* inflate and deflate polygons
|
|
* with Min Thickness/2, and merges the result (like initial algo)
|

* The remaining polygons are areas with thickness < min thickness
|
