By 'root lines' we mean the oldest traceable ancestor of each track moved by the router
(i.e. after shoving for a while, the root of each shoved line is it's latest non-shoved version).
With this we can teach the OPTIMIZER more tricks, such as the LIMIT_CORNER_COUNT constraint. It ensures
the results of the optimization will not be less cornery than the original line, reducing the feeling
of the optimizer being too intrusive.

REMOVED: Update schematic option from geographical annotation dialog due
to potential issues with incomplete and/or broken updates. Use "Update
Schematic from PCB" tool to update reference designation changes.
Forcing the footprint reference designator changes back to the schematic

schematic in a undefined state. The update schematic from board tool is
the correct method to sync any changes from the board.

This is a work-in-progress. It could use testing while I continue to fix
the remaining pieces.
There are some changes that will be needed for signing and notarization.
This currently relies on a Python tool I wrote (dyldstyle) to fixup
KiCad.app correctly. I would like any bundle fixing necessary to use a
built KiCad on macOS to live inside KiCad, rather than in
kicad-mac-builder or elsewhere. While I was experimenting, I found this
worked, however, and I would love to get extra hands testing.
I added a CMake argument, MACOS_EXTRA_BUNDLE_FIX_DIRS, for devs and
packagers who have extra directories they need to add to
fixup_bundle on KiCad.app.
There's an issue about differing behavior when KiCad is opened via
the command line or via Finder/launchd.
From discussion with Tom, Jeff, and Wayne, it appears as though
we all agreed that Highlight Collisions should behave like it
did in 5.1, which is to say, always just highlight collisions,
never prevent them. The Allow DRC Violations checkbox just
controls whether or not you can fix/commit the head line if it
has violations; you are not prevented from moving the head
line to violating positions in any case.
Right now, there does not seem to be much demand for a separate
"Stop at First Obstacle" mode since Walkaround basically does that
but better, but we agreed that if there is demand for it in the
future, it should be implemented as a new router mode rather than
a behavior of Highlight Collisions mode controlled by the Allow
DRC Violations checkbox.

When creating a polygon from an arc/circle, the small error due to approximation
can be now inside (when drawing/plotting the shape) or outside the circle
(when building a clearance area) like other pad shapes
Fixes#5313https://gitlab.com/kicad/code/kicad/issues/5313
Using a synthetic via here doesn't quite let us use VIA::PushoutForce
because it will use the wrong clearance, and also doesn't quite have
the logic we want. I am not familiar enough with PushoutForce to know
if its logic is a bug in other cases, so instead I just brought in the
parts of its algorithm that are needed here.
Additionally, we prevent pushing more than once from a given obstacle,
which causes walkaround to be more successful when routing diff pairs
against a large collider such as a keepout area.

I'm not sure where the magic number of "4x worst" came from, but it's
been around forever. This is extremely inefficient as it negates much
of the power of r-tree filtering in dense designs. If we really trusted
it, we could set this just to worstClearance. Keeping it above the worst
clearance by a little bit seems to provide enough of a speed improvement
to resolve the test cases I have, so I'll go with that for now.

VIEW::GetBoundary() returns the entire view area, not the visible area.
Surprisingly, we had no API for this, so I added one.
Also, changed the dragger behavior to toggle between optimizing just the
modified area and optimizing the visible area, i.e. we will now never
optimize off-screen portions of the dragged track.
CHANGED: The interactive router settings now include a switch to
enable or disable optimization of the entire dragged track,
which is now disabled by default. When enabled, the router
will reroute the entire track (from the dragged segment to
the closest pad/via in each direction) to be more optimal.
When disabled, only the area around the dragged segment
will be modified.
CHANGED: The "optimizer effort" slider is removed from the interactive
router settings dialog, as this setting did not have any
meaningful impact in most cases and was a source of confusion.

The thickness only needs to be computed when the actual

When expanding an error to the outside of a rounded corner pad we
need to trim it to the pad bounding box or else we get little ears
where the circle approximation meets the pad square. This is expensive,
and for clearance lines we don't really care whether the error is
inside or outside.

Instead of enabling/disabling the controls on every possible
UI event in these dialogs, only do it when the actual control
wants to know if it should change status.
This code was shared between the footprint frame and
pcb edit frame, so push it into the base edit frame.
Also remove the dummy wxUpdateUIEvents that weren't
actually being used.
Use the connecting straight tracks even if not exactly parallel - allow
an error margin configurable in ADVANCED_CFG (default 1 degree). Also
be less strict about end point matching and use the width of the track
as the criteria to determine suitability.
Finally, delete any short lengths of track at the end of the operation
and amend the arc end points to keep connectivity.

The angle was `-angle` instead of `180 deg - angle` when flipping top to
bottom.
Fixing that, in turn, created some problems with justification, which
was modified both by `FP_TEXT::Flip()` and `FP_TEXT::KeepUpright()`.
What's worse, `FP_TEXT` has another mechanism for keeping the text
upright: `FP_TEXT::GetDrawRotation()` returns different angles if the
"keep upright" flag is set. But there is no analogous behavior for
justification, so the text would sometimes get shifted, and sometimes
not, depending on which mechanism was engaged. And both are used,
apparently.
Clearly, such an arrangement an open invitation to bugs and
inconsistencies. One of these mechanisms should be removed. I haven't
done this yet, and would prefer to postpone this until V6 is out.
I've fixed the justification problems, but this was by trial-and-error,
and I don't feel I really understand the behavior responsible. But I
think it's a good sign that most of my changes are line removals, not
additions. Flipping is a simple operation, it's just mirroring and layer
change. If something simple has a complicated routine, then it's
probably full of hacks.

This is under the supposition that we can't set the column widths

It is still possible to move a pad independent of footprint through
the pad properties dialog. This is a much more conscious decision
than using the move tools.
ADDED: "Allow free pads" preference setting in pcbnew, default to off.
When enabled, allows moving unlocked pads independent of the footprint
(i.e. previous behaviour). When disabled (default), any attempt to move
a pad will move the parent footprint instead.
REMOVED: "Lock pads of newly added footprints" preference setting in
pcbnew. (Pad lock state is now loaded from the footprint definition)
CHANGED: There are now only two possible lock states for a footprint:
locked and unlocked. The lock state of the pads in the footprint is
now independent of the footprint lock state.
Also fixed a latent bug that would allow a pad to be moved when the
parent footprint was locked (see m_selectionTool->RequestSelection
lambdas in edit_tool.cpp)

After commit 9535153f9e there were no more IDs inside the legacy ID
system. Therefore the entire system for dispatching and looking up
the legacy ideas and handling those events can now be removed and
the tool dispatcher simplified (it no longer needs to know about
the ACTIONS class).
Loading this advanced configuration option statically will cause it to
show up in the hotkey list even when the option is disabled. Creating
the tool action at run time resolves this issue.
This is hidden behind an advanced configuration setting and is primarily
useful for developers trying to troubleshoot the netlist payload sent
from the board editor to the schematic editor.

The ACTION_MENU constructor now takes the tool as an argument,
so the call to SetTool() immediately following it can be removed
and the tool just passed into the constructor.
Saying "Import/Export" on the labels when the submenu has "Import"
or "Export" in it is redundant.
Note that we can't just update the action text with the new name,
because that is used in the hotkey list and would become too confusing
without the "Import"/"Export" text.
The text areas aren't always redrawn when the window is activated
or deactivated, so we need to force a refresh of the text to ensure
it is the correct font color.

KiCad doesn't yet support full padstacks, but at least we can use the
solder mask / solder paste expansion to import a better result. Also
we can disable the specific layer if the shape has a size of zero.
The CADSTAR post processor has a peculiar feature called "route offset"
which effectively shortens tracks when the pad, track or via that it
connects to has a smaller width. This operation is not saved in the
design itself, but applied as a post processing operation meaning that
the importer has to apply it when loading on the board.

only start to drift apart. Board Setup should validate for malformed

Old boards were using UNDEFINED_DRILL_DIAMETER value in file for via drill when
the via drill value was the netclass value.
Recent boards always set the via drill to the actual value, but now we need
to be sure always store the drill value, because netclass value is not stored
in the board file. Otherwise the drill value of some (old) vias can be unknown
The rotate mirror actions need to line up with the expectation.
FABMASTER keeps elements board-referenced while KiCad has some elements
referenced to the board and some referenced to the footprint
wxWidgets' UTF8 mode wasn't thread-safe, so we had to put mutex's on
a bunch of string operations, which meant that we couldn't return
references to strings. Now that we no longer use UTF8 mode anywhere
(and the mutex's were removed long ago), using references is a big
performance win in some places.
Between the time the user loads the footprint preview in cvpcb or Add
Footprint in pcbnew, we don't need to verify cache integrity to display
the footprint. We use the cache copy when displaying until we close the

full directory on every footprint display.
Alternate solutions for v7 should include looking into libfswatch for
change detection

Each symbol unit in eeschema has a unique identifier. But we don't have

This simple commit makes the Pcbnew copy to clipboard operation snap the
obtained cursor position to grid before the anchors are calculated. This
is also the way the move operation has been apparently working so far.
To be clear, this will not remove all cases where the copy reference
point is not aligned to the grid (see the linked Gitlab issue for
details about the problem). This will still occur for zone outlines that
are not axis-aligned. But such behavior has been so far also present in
the moving operation, so this may be as designed.

For some kinds of issues, we want a way to point them out but
we don't need to keep the user from being able to close the

be ignored if the user wishes.
The removal of the pcbnew general section was meant for v6 but passed
the deadline. This removes the duplication of thickness. We do not
allow the thickness to be different between nominal and stackup, so
keeping separate text fields is unnecesarily confusing to users
The automatic wire tool was not working in the gridless mode because the
grid snapping on/off logic present in `EE_GRID_HELPER`, based on the
value of `m_enableGrid`, was not taking into account that another check,
but for the global KiCad setting, would be performed in the `Align()`
method, which is inherited from `GRID_HELPER`.
I've modified all tests of `m_enableGrid` value to also take the global
setting into account, and moved checks for it to `Align()` method, as
it's more consistent this way.
I've also removed an override of the `Align()` method in the
`PCB_GRID_HELPER` class, as it was made redundant by my changes.

Some CADSTAR designs use zero sized pads because CADSTAR did not allow
