Clean up arc/circle polygonization. 1) For a while now we've been using a calculated seg count from a given maxError, and a correction factor to push the radius out so that all the error is outside the arc/circle. However, the second calculation (which pre-dates the first) is pretty much just the inverse of the first (and yields nothing more than maxError back). This is particularly sub-optimal given the cost of trig functions. 2) There are a lot of old optimizations to reduce segcounts in certain situations, someting that our error-based calculation compensates for anyway. (Smaller radii need fewer segments to meet the maxError condition.) But perhaps more importantly we now surface maxError in the UI and we don't really want to call it "Max deviation except when it's not". 3) We were also clamping the segCount twice: once in the calculation routine and once in most of it's callers. Furthermore, the caller clamping was inconsistent (both in being done and in the clamping value). We now clamp only in the calculation routine. 4) There's no reason to use the correction factors in the 3Dviewer; it's just a visualization and whether the polygonization error is inside or outside the shape isn't really material. 5) The arc-correction-disabling stuff (used for solder mask layer) was somewhat fragile in that it depended on the caller to turn it back on afterwards. It's now only exposed as a RAII object which automatically cleans up when it goes out of scope. 6) There were also bugs in a couple of the polygonization routines where we'd accumulate round-off error in adding up the segments and end up with an overly long last segment (which of course would voilate the error max). This was the cause of the linked bug and also some issues with vias that we had fudged in the past with extra clearance. Fixes https://gitlab.com/kicad/code/kicad/issues/5567

/* 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.

Clean up arc/circle polygonization. 1) For a while now we've been using a calculated seg count from a given maxError, and a correction factor to push the radius out so that all the error is outside the arc/circle. However, the second calculation (which pre-dates the first) is pretty much just the inverse of the first (and yields nothing more than maxError back). This is particularly sub-optimal given the cost of trig functions. 2) There are a lot of old optimizations to reduce segcounts in certain situations, someting that our error-based calculation compensates for anyway. (Smaller radii need fewer segments to meet the maxError condition.) But perhaps more importantly we now surface maxError in the UI and we don't really want to call it "Max deviation except when it's not". 3) We were also clamping the segCount twice: once in the calculation routine and once in most of it's callers. Furthermore, the caller clamping was inconsistent (both in being done and in the clamping value). We now clamp only in the calculation routine. 4) There's no reason to use the correction factors in the 3Dviewer; it's just a visualization and whether the polygonization error is inside or outside the shape isn't really material. 5) The arc-correction-disabling stuff (used for solder mask layer) was somewhat fragile in that it depended on the caller to turn it back on afterwards. It's now only exposed as a RAII object which automatically cleans up when it goes out of scope. 6) There were also bugs in a couple of the polygonization routines where we'd accumulate round-off error in adding up the segments and end up with an overly long last segment (which of course would voilate the error max). This was the cause of the linked bug and also some issues with vias that we had fudged in the past with extra clearance. Fixes https://gitlab.com/kicad/code/kicad/issues/5567

Clean up arc/circle polygonization. 1) For a while now we've been using a calculated seg count from a given maxError, and a correction factor to push the radius out so that all the error is outside the arc/circle. However, the second calculation (which pre-dates the first) is pretty much just the inverse of the first (and yields nothing more than maxError back). This is particularly sub-optimal given the cost of trig functions. 2) There are a lot of old optimizations to reduce segcounts in certain situations, someting that our error-based calculation compensates for anyway. (Smaller radii need fewer segments to meet the maxError condition.) But perhaps more importantly we now surface maxError in the UI and we don't really want to call it "Max deviation except when it's not". 3) We were also clamping the segCount twice: once in the calculation routine and once in most of it's callers.
