Detailed Description

Functions to plot one board layer (silkscreen layers or other layers).

Silkscreen layers have specific requirement for pads (not filled) and texts (with option to remove them from some copper areas (pads...)

◆ NEW_ALGO

#define NEW_ALGO 1

Plot a solder mask layer.

Solder mask layers have a minimum thickness value and cannot be drawn like standard layers, unless the minimum thickness is 0. Currently the algo is: 1 - build all pad shapes as polygons with a size inflated by mask clearance + (min width solder mask /2) 2 - Merge shapes 3 - deflate result by (min width solder mask /2) 4 - ORing result by all pad shapes as polygons with a size inflated by mask clearance only (because deflate sometimes creates shape artifacts) 5 - draw result as polygons

We have 2 algos: the initial algo, that create polygons for every shape, inflate and deflate polygons 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) remove all initial polygons. The remaining polygons are areas with thickness < min thickness plot all initial shapes by flashing (or using regions) for pad and polygons (shapes will be better) and remaining polygons to remove areas with thickness < min thickness from final mask

TODO: remove old code after more testing.
