This also removes vector cover types which do nothing except obfuscate
the underlying implementation.
Mainly changes SCH_SHEET_PINS and CONFIG_PARAM_ARRAY (which will soon
be replaced by Jon's new stuff).
This moves EESchema DLIST structures to rtree. These changes are more
fundamental than the pcbnew changes from 9163ac543888c01d11d1877d7c1
and 961b22d60 as eeschema operations were more dependent on passing
drawing list references around with SCH_ITEM* objects.
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
Add missing check for root sheet when searching sheet hierarchies for
already loaded schematics. This prevents the root sheet from being
omitted when adding new sheets using the root sheet file name.
CHANGED: Make file name tests case sensitive so that schematic sheet
file names on non-Windows systems can be uses as expected.
Warn users when attempting to use schematic file names that only vary
by case sensitivity that doing so will result in a project that is not
portable to Windows.

1) When sheet pins are on 3 or more sides there's no point in switching
the orientation to vertical.
2) Careful that we don't cause the sheet to walk when rotating and the
sheet-name or file-name is longer than the side it's on.

No dangling symbol for text items with a NO-CONNECT.
DanglingStateChanged doesn't work with dangling flag aggregators
(which return true if any child is dangling).
Then again, we don't actually use any of the aggregators anyway

Take field name sizes and user preference line thickness into account
when calculating placement of the text fields of a hierarchical sheet on
the canvas.
The previous calculations contained some magic numbers which seem to
have been well suited to cases where line width is 8 and text size is
0.050. However, the text collided with the sheet outline as soon as text
size or line width was increased.
This commit has been evaluated with line widths ranging from 5 to 100
and text sizes ranging from 0.02 to 0.200. Also in combination with
characters such as qyg and ÅÄÖÜ in the file/sheet names.
(cherry picked from commit b1a60b2)
When drawing a hierarchical sheet symbol, the text line width for
"Sheet: ..." and "File: ..." are now clamped (limited).
Clamp_Text_PenSize() is used for the calculation.
Before, without the clamping, these text widths grew with the line width
preferences option. That resulted in characters cluttering up.

All of the schematic object load and save code is implemented in the
legacy schematic plugin so it is no longer required.
Remove unused file with old schematic file loader.
Doxygen comment cleaning.
Use sheet pin direction to calculate sheet minimum height and width.
Remove sheet pin offsetting as the new sheet height and width calculation
prevents invalid minimums.
Calculate the proper minimum height when resizing sheets to prevent resized
sheet height from always increasing.
Prevent the sheet pins from being drawn in the corners of the sheet when
updating the edge constraints on resize. This ensures that the sheet pin
is always drawn within the bounds of the sheet. Please note that this fix
may not be 100% accurate as is assumes the default grid size of 50 mils.
This may not be what the user expected but it guarantees that wires will
connect to the pin properly.

eeschema now supports arbitrary colors for all object types, and
pcbnew does in GAL canvas. When switching from GAL to legacy canvas,
pcbnew will convert colors to the nearest legacy color.
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.
Make all EDA_TEXT data private and rename accessors to avoid function
name collisions in derived classes.
Overload EDA_TEXT's SetTextAngle() and SetEffects() in TEXTE_PCB.
Add support for preserving Reference text position, size, orientation
during a netlist import into a BOARD, as well as the one off footprint
update dialog.
* Factor out PROPERTIES object from the PCB plugin code and move it into
common so it can be used by both the Pcbnew and Eeschema plugins.
* Add schematic I/O plugin manager for loading and saving schematic and
component library files.
* Add initial attempt at a parser for current schematic file format. This
parser will be infinitely more strict than the current parser which is very
forgiving in what it parses.
* Make minor changes to the base bitmap class to support the new parser.
* Add find root sheet support to sheet object to allow fetching the root
sheet from any sheet in the stack.
* remove duplicate code between draw functions and STROKE_FONT used in GAL. Use only STROKE_FONT methods in draw, plot and test DRC function for texts. It remove slightly different shapes between GAL and other calculations.
* fix incorrect bounding box for texts with overbar. Especially noticeable for texts with overbar inside a copper zone in Pcbnew.
* fix a few minor other bugs related to graphic texts.
* On MinGW64 and possibly other 64-bit platforms, time_t is defined as a long
long unsigned integer but all of the scanf and printf format specifiers used
to save and load the schematic files are %lX which is a long unsigned integer
which causes compile warnings. Add casts and temporary variables to eliminate
the compile type warnings.
* Derive SCH_SHEET_PATH from std::vector< SCH_SHEET* > and remove unnecessary
assignment operator and list management functions.
* Remove function BuildSheetPathInfoFromSheetPathValue() since it was
effectively an assignment operation.
* Replace all calls to BuildSheetPathInfoFromSheetPathValue() with assignment
operator.
* Replace list management functions with vector management functions.
* Fix a error message that wasn't translatable.
* Ensure proper SCH_SHEET object page numbering which caused annotation to
calculate incorrect reference designators when annotating by using page offsets.
* Added SetPageNumbers to SCH_SHEET for setting sheet page numbers after
schematic is loaded.
* Move FindSheetByName() function from SCH_SHEEET_PATH to SCH_SHEET object
and update calls to FindSheetByName() accordingly.
* Remove SCH_SHEET_PATH::FindSheet() which was unused.
* Add sorting option to SCH_SHEET::GetSheets().
* Add const and non-const version of GetRootSheet() to SCH_SHEET.
* Add GetSheetPaths() function to SCH_SHEET which behaves the same way
as SCH_SHEET_LIST except it uses standard C++ containers and is a much
simpler design.
* Add function to get a list pointers to this sheet and all of it's sub-sheets
to SCH_SHEET.
* Remove unused function SetFootprintField() from SCH_SHEET_PATH.
* Add sheet number that is set by schematic file load order. This duplicates
the previous SCH_SHEET_PATH behavior.
* Uncouple SCH_REFERENCE and SCH_REFERENCE_LIST from SCH_SHEET_PATH.
* Add - operator to SCH_SHEET for comparison purposes. This duplicates the
behavior of SCH_SHEET_PATH::Cmp().
* Uncouple SCH_COMPONENT::GetRef() from SCH_SHEET_PATH and use SCH_SHEET
instead.
* Uncouple SCH_COMPONENT::GetUnitSelection() from SCH_SHEET_PATH and use
SCH_SHEET instead.
* Fix all calls to GetRef() and GetUnitSelection() to pass a pointer to the
appropriate SCH_SHEET object instead of an SCH_SHEET_PATH object.
* Add code to SCH_SHEET object to clear annotation.
* Change SCH_COMPONENT::GetPath() to derive path from SCH_SHEET object instead
of SCH_SHEET_PATH object.
* Remove clear annotation code from SCH_SCREENS object.
* Make SCH_SHEET parent the SCH_SHEET object that loaded it. This preserves
the hierarchy when the schematic is loaded.
* Add function to SCH_SHEET to find the root sheet from any sheet in the
hierarchy.
* Add functions to SCH_SHEET to create the path and human readable paths for
any sheet without relying on the external SCH_SHEET_PATH object.
* Remove function LocatePathOfScreen from SCH_SHEET since it was not used
anywhere.
* Add human readable path to message panel information for SCH_SHEET.
* Set the name of the root sheet to "root" instead of the default generated
when a new SCH_SHEET is created.
* Set the empty sheet name and file name to "root" and "noname.sch" when
Eeschema is opened with no schematic.
* When no item is at the current position on a left mouse click, show the
current sheet information in the message panel.
* Add less than operator for sorting SCH_SHEET objects by path length and
time stamps when the path lengths are the same.
Move items rework: enhancements: for some items (sheets, components, bus entries) the mouse cursor is no more wrapped to the anchor. For large symbols, this is better: they are more easy to place.
There is also a change when starting a move item command: the full screen is redraw, and therefore there is no artifact due to the XOR draw mode.
Some other minor coverity fixes (uninitialized members).
* move not shared files (sch_item_struct.*, sch_base_frame.h) to eeschema;
* move wxEeschemaStruct.h to eeschema and rename it schframe.h to be consistent with the other corresponding file name schframe.cpp;
* remove few not needed #include
* Make title capitalization consistant.
* Replace some instances of module with footprint.
* Use angle instead of orientation where appropriate.
* Remove abbreviations where it made sense.
* Coding policy fixes.
*) When kicad.exe closes a project, close any open KIFACEs so that they cannot
get disassociated from their true PROJECT.
*) Allow loading eeschema library editor from kicad.exe
*) Allow loading pcbnew library editor from kicad.exe
*) Rename LIB_COMPONENT to LIB_PART.
*) Add class PART_LIBS, and PART_LIB.
*) Make PART_LIBS non-global, i.e. PROJECT specific.
*) Implement "data on demand" for PART_LIBS
*) Implement "data on demand" for schematic SEARCH_STACK.
*) Use RSTRINGs to retain eeschema editor's notion of last library and part being edited.
*) Get rid of library search on every SCH_COMPONENT::Draw() call, instead use
a weak pointer.
*) Remove all chdir() calls so projects don't need to be CWD.
*) Romove APPEND support from OpenProjectFiles().
*) Make OpenProjectFiles() robust, even for creating new projects.
*) Load EESCHEMA colors in the KIWAY::OnKiwayStart() rather in window open,
and save them in the .eeschema config file, not in the project file.
*) Fix bug with wxDir() while accessing protected dirs in kicad.exe
*) Consolidate template copying into PROJECT class, not in kicad.exe source.
*) Generally untangle eeschema, making its libraries not global but rather
held in the PROJECT.
! The initial testing of this commit should be done using a Debug build so that
all the wxASSERT()s are enabled. Also, be sure and keep enabled the
USE_KIWAY_DLLs option. The tree won't likely build without it. Turning it
off is senseless anyways. If you want stable code, go back to a prior version,
the one tagged with "stable".
* Relocate all functionality out of the wxApp derivative into more finely
targeted purposes:
a) DLL/DSO specific
b) PROJECT specific
c) EXE or process specific
d) configuration file specific data
e) configuration file manipulations functions.
All of this functionality was blended into an extremely large wxApp derivative
and that was incompatible with the desire to support multiple concurrently
loaded DLL/DSO's ("KIFACE")s and multiple concurrently open projects.
An amazing amount of organization come from simply sorting each bit of
functionality into the proper box.
* Switch to wxConfigBase from wxConfig everywhere except instantiation.
* Add classes KIWAY, KIFACE, KIFACE_I, SEARCH_STACK, PGM_BASE, PGM_KICAD,
PGM_SINGLE_TOP,
* Remove "Return" prefix on many function names.
* Remove obvious comments from CMakeLists.txt files, and from else() and endif()s.
* Fix building boost for use in a DSO on linux.
* Remove some of the assumptions in the CMakeLists.txt files that windows had
to be the host platform when building windows binaries.
* Reduce the number of wxStrings being constructed at program load time via
static construction.
* Pass wxConfigBase* to all SaveSettings() and LoadSettings() functions so that
these functions are useful even when the wxConfigBase comes from another
source, as is the case in the KICAD_MANAGER_FRAME.
* Move the setting of the KIPRJMOD environment variable into class PROJECT,
so that it can be moved into a project variable soon, and out of FP_LIB_TABLE.
* Add the KIWAY_PLAYER which is associated with a particular PROJECT, and all
its child wxFrames and wxDialogs now have a Kiway() member function which
returns a KIWAY& that that window tree branch is in support of. This is like
wxWindows DNA in that child windows get this member with proper value at time
of construction.
* Anticipate some of the needs for milestones B) and C) and make code
adjustments now in an effort to reduce work in those milestones.
* No testing has been done for python scripting, since milestone C) has that
being largely reworked and re-thought-out.
Pcbnew: Code cleaning and bug fix in autoplace functions
Dialog exchange footprints has now a separate button to update the .cmp file, only on request.
Fix an annoying issue about not named nets:
now, these nets are named from the component references and pin names which are connected.
therefore, unless the net or the footprint references are modified, the net name is not modified between 2 netlist calculations.
In particular the new mechanism for handling extended color palettes is in place,
included renaming the ini keys and saving the color name instead of its index; this means better forward compatibility with palette changes.
Since ini keys are changed, colors will be reset
* Complete encapsulation of the MODULE class.
* Complete encapsulation of the EDA_TEXT class.
* Encapsulate most of the ZONE_CONTAINER class.
* Add pcbcommon library as a dependency for reSWIGging the scripting
support. This should cover most dependency cases.
* Improve MSG_PANEL_ITEM to handle message panel information.
* Create containers for passing message panel items between objects and
the message panel.
* Rename EDA_ITEM::DisplayInfo to EDA_ITEM::GetMsgPanelInfo.
* Remove all direct manipulation of EDA_DRAW_FRAME from all objects derived
from EDA_ITEM.
