The thermal spokes are anchored at the pad anchor. They may or may
not make sense, depending on the pad shape. It's up to the author
to move the anchor around as necessary or to not use thermals.
This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments. This allows the user to customize their speed vs. accuracy
tradeoff. The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.
This removes the remaining hard-coded segments counts and replaces them
with the relative error calculation where the segments per arc is
determined by the maximum error we allow (smaller arcs = fewer segments)
1 - For debug purposes, the code to fill non copper zones was disabled and the copper zone code was uses instead.
It creates issues with pad clearance areas, because a non copper zone has no clearance areas.
2 - The non copper zone dialog had no option to set the outline smoothing option.
Unfortunately, this parameter was inherited from the last edited copper zone.
And therefore the non copper zone can have a non wanted outline smoothing option.
This option is now added to the dialog.

Give the user the option of cancelling a file open if there are
segment zones; otherwise they're converted to polygon fills.

For legacy boards, the setting is picked up from the board outline
thickness. If the board outline has mixed thicknesses, then the
max is used and a warning is displayed.

the filled areas can use a hatch pattern (crossing lines) using square holes.
The zone filler removes too small holes (truncated holes) from hatch pattern.
It avoid to create small holes when a hole pattern is truncated by the filled area base shape.
Commit 6006703798 fixed a crash but broke the filled zones changes detection.
Filled zones were always seen as not up to date due to the fact the filled areas were cleared too early.
The up to date detection is also optimized: the old filled polygons are no longer stored.
Instead of, the MD5_HASH is calculated and stored before clearing the filled polygons.
Previously, in many cases the selected zone was refilled on exit selection, even if the zone was not modified.
This is annoying, because the zone fill can be really time consuming, and cannot be called without a good reason.
Now the refilling is made only if a zone parameter is actually modified.
Removing existing fills will prevent re-drawing invalid polygons before
they are ready. This seems to happen on Macs more easily due to redraw
timing.

This was due to the stub removal tests if a stub end is outside a solid area to remove it.
There is a corner case: is the stub end is exactly on a solid area outline extra segment
created by Fracture() used in calculations.
The stub removal tests are now made before fracturing.

No net zones, by definition, do not connect to any other element.
Therefore, the entire net is an island and should not be removed by the
knockout section

Non-connected zones are, by definition, not connected, therefore, we

Where we can get away with lower segment counts (localizing an anchor),
we keep the low-def 16 segment count. Intermediate values and values
that are visible to the user are set to high definition. Most are
simply hints to the inflation correction but where they show, the user
show see smooth lines.
Most rounding operations have been shifted to an absolute error
calculation and the ability to adjust zone segment counts has been
removed in 5.1. The remaining elements that use fixed segment counts
are either 18 (DRC) or 32 (plotting). This aligns the punchout segment
count with the higher (32) definition value
Rather than depend on proper unlocking for each exit, we move the
connectivity lock mutex into an RAII-type configuration that
automatically unlocks on exit.
This allows people to continue to use the edge-width as a proxy
for board edge clearance until we implement board edge clearance
as a real feature.

The evaluation of count_if resulted in a 0 or 1, leading to segment zone
fills always running on single processor and the progress bar showing
incorrect status. Likely infrequently hit as only affected segment
fills.
This is a boyscouting commit to standardize the threading of zone fills.
We do not need to join threads after their completion, instead we simply
allow them to clean up their memory without blocking the user. This
also sets the maximum number of threads that may be created to the
number of zones being filled. More than this will only leave un-used
threads being created and immediately killed.
We also include the connectivity search as a phase in the fill progress
reporter. This was the case before but did not utilize the correct
maxsize, leading to stalled progress bar.
Using Title + Message wasn't working for all the dialogs which
did substitutions in the message (which was a lot of them).

There are three related changes here to harden our handling of threads
in the footprint async loader.
1) Footprint async loader explicitly aborts any remaining loader threads
on exit.
2) We protect the thread join by a mutex
3) We do not pause during no-wait routines
m_Zone is a fully deprecated list of SEG_ZONE items (similar to TRACK), used to fill copper zones in *very old* boards.
it is even unlikely there are still boards that use them.
So it should be removed one day.
On OpenMP single core systems only the first thread launched. It means
that only the UI updating thread was running, without the one
responsible for actual computation. It is fixed by enforcing at least
two threads.
The calculation was made too early, before removing insulated islands.
Note: filling zones with segments is an old option, not very useful:
using only polygons has never created issues in gerber files.
