Launching right click context menu overrides the cursor position, so all

PICKED_ITEMS_LIST knows the architecture of the undo commands so
that it can delete those ITEMs which it owns. This represents poor
encapsulation so instead of adding yet another case, I added a
UR_TRANSIENT item flag which is set by callers whenever they create
new objects to “give to” the undo/redo stack. This allowed some
cleanup of other code, but cleaning up UR_DELETE and UR_WIRE_IMAGE
will be a bigger task and have to wait for another day.

The undo/redo operations are essentially the same as for
UR_CHANGED: we store both the origin marker item and a copy
of it and flip back and forth between the two. This also
required the implementation of clone() for the markers.
The ORIGIN_VIEWMARKER is moved from being a subclass of
EDA_ITEM to BOARD_ITEM to facilitate the use of a UR_CHANGE-
like implementation without having to know the internals
of the ORIGIN_VIEWMARKER.
In the command processors, the setting of the origins is
broken into two parts: one for UI-level access which includes
setting up undo, and one for low-level access which does not.
The undo/redo code itself of course uses the lower level.

A change in commit 5731000135 caused kicad to stop allowing users
to move items like footprints, arcs and lines using anchors other
than the center point.
This was caused by the new code that stores reference points for
clipboard pasting, a call to updateModificationPoint() prevented
some old code paths from executing, which caused the selection to
snap into the cursor, always using the center anchor.
This fix moves the call within the if-cases that need it, and adds
a ClearReferencePoint call when the selection is "dropped" to allow
the user to grab the same selection again from a different anchor.

Removes the need of using the legacy code in polygon/PolyLine.{h,cpp},
refactoring all CPolyLine instances with SHAPE_POLY_SET instances.

The iteration over the polygon vertices have been simplified using the

The zone creation in DRAWING_TOOL was a complex event loop whici
simultaneously managed the event handling, construction of the preview
polygon and the creation and commiting of the zone, all in the same
scope. This has been broken into several pieces:
* POLYGON_ITEM preview item, used to preview the polygon in progress
* POLYGON_GEOM_MANAGER is a class that collects points from user input
and used them to describe a polygon's geometry, including calculation
of 45-degree constrained leader lines
* ZONE_CREATE_HELPER is a class which deals with creating zones based on
geometry from a geometry manager and parameters from the DRAWING_TOOL
* The (much simpler) event loop in DRAWING_TOOL drives the
POLYGON_GEOM_MANAGER. With a minor refactor, this loop can be reused
in future for other polygonal tools if wanted.
The polygon preview now has a translucent fill which makes it easier to
visualise the zone.
This also adds the Close Zone Outline and Delete Last Corner actions as
part of the new event loop.

This uses the two-point geometry manager to split the logic of the ruler
geometry and the preview item display. This allows the ruler to use that
manager's angle snap feature.
The motivation here is to concentrate display options in the GAL display
settings, ready for removal of legacy canvases. Instead of having the
property as a member of the DRAW_FRAME, with the GAL canvas retreiving
it from there, it is now in the GAL_DISPLAY_OPTIONS struct, and both GAL
and legacy get it from there.
The options for setting cursor shape are then moved out of the general
options dialog, and into the GAL display options widget, where they can
be used in all GAL-aware programs.
GAL cursor shape works on GAL, but not legacy, so the option is now
available on OSX (but only affects GAL, and is labelled as such).
This adds the microwave tools to GAL in Pcbnew as a new tool:

* CENTRELINE_RECT_ITEM a preview item to draw ractangle with a given
aspect ratio along a line (specified using a TWO_POINT_GEOM_MANAGER)
PCB_TOOL gets a generic event loops which should be useful for more
than just microwave tools:
* doInteractiveItemPlacement() - handles event loops that wait for a
click, create an item on click and then allow moving it
around/flipping, etc.

* MULTISTEP_GEOM_MANAGER: represents a generic "geometry manager" that
builds up some geometrical construction based on a sequence of points.
Used by:

BOARD::GetBoundingBox() now directly calls BOARD::ComputeBoundingBox()

Adds a similar crossprobe as modules has in pcbnew. When clicking a

Some grid/zoom tools are left in PCBNEW_CONTROL because they currently

bitmaps.h was included in nearly every file in the project due to it
being included by base_struct.h
Only about 130 files actually use the XPM definitions defined there, and
many of those already included bitmaps.h themselves, or via
menu_helpers.h. However, touching bitmaps.h would result in over 400
rebuilt files for pcbnew alone.
This commit moves the bitmap-related types like BITMAT_DEF out to a new
header, which is still included by base_struct.h, which is less
avoidable for now, it's it's used in the interface.
The icon list is still in bitmaps.h. This has the side effect that's
it's now easier to automatically generate this file.
Many classes in pcbnew and eeschema needed some functions moved
to the implementaitons from the headers too.
The apply settings and push settings options now take account of the

This patch fixes a problem with GAL where zones are ignored in ratsnest
calculation.
The problem is that calling RN_DATA::Update on a zone with no polygons
(an unfilled zone) will remove the zone successfully, but then
RN_DATA::Add is a no-op.
From this point on, because ::Update refuses to work on items that have
not been ::Add'ed, the zone is removed entirely from ratsnest
calculation and will only be reconsidered once it is explicitly ::Add'ed
again.
The fix is to explicitly create an empty RN_ZONE_DATA object for every
zone that is ::Add'ed.
A second problem is that the point editor forgot to call
RN_DATA::Recalculate after calling Fill_Zone.

belonging to subsheets. It will also search for nets that are only

This action launches the normal interactive zone tool, but re-uses the

Break a chunk of the new zone tool out into a separate function to keep
the code clear. When zone cutouts and similar zone tools are added,

This commit now used std::unique_ptr for the temporary zone item, which

This commit wires up the as-yet-unused "remove alternate" tool action

THis also reverses the sense of Delete and Backspace (Delete used to be
'remove' and Backpace was 'remove alt', now it is reversed). This means
that backspace is the key that removes a segment and Delete removes the

There used to be a number of TOOL_ACTIONs that had entries both in
SetTransitions() and the event loop, which seemed redundant and
troublesome.
Now it is not necessary anymore, transitions setup is enough to execute
associated actions.
The problem with simple deleting VIEW_ITEM_DATA upon VIEW_ITEM removal was
caused by the default copy constructors that copied pointers.
Once a copy of an item was destroyed, the VIEW_ITEM_DATA has been
destroyed, effectively invalidating m_viewPrivData for the other item.
This means that non-top-level tools, for example EDIT_TOOL and
PCB_EDITOR_CONTROL can submit their own menus to the top-level tool's
TOOL_MENU, which will then retain a reference to it and make it
available for the CONTEXT_MENU that is shown.
Add a class TOOL_MENU, which provides a management class for a
CONDITIONAL_MENU and a set of CONTEXT_MENUs. The aim of this is to
provide a central place where all TOOL_INTERACTIVEs can get a "basic"
context menu that either they or other tools can register new items and
sub-menus against.
This means that "top-level" tools no longer need to manage the lifetimes
of any CONTEXT_MENUs that they add, and can also delegate simple menu
display functions.
If the SELECTION_TOOL's Select... menu is not shown, the separator under
it should also not be shown, so use the same SELECTION_CONDITIONS to
enforce this.
The GAL line segment tool now listens to the global line segment 45
degree locking preference, with Ctrl used to invert the behaviour. The
behaviour therefore follows the setting normally, and the user can
override when needed with Ctrl.
