It should help if (or when) the internal angle unit used in kicad will be changed from 0.1 degree (a relic of code written for PCs without fpu) to degree ( a more natural unit).
Fix erroneous optimization in VECTOR2<T>::Rotate (which was made for angles in degrees): Angles are in radians, and only 0 rd rotation is skipped ( case very frequent, especially in eeschema)
* Add event handler to check all button clicks for default command event
IDs and handle them appropriately by either calling EndQuasiModal() or
passing the event up the event handler chain to allow the default dialog
handlers to perform their magic.
* Add event handler to handle the close window event properly.
* Add scope brackets so the wxBusyCursor will stop being displayed when
the footprint library loading is complete in CvPcb.
The new (eeschema, so far) hotkeys editor uses the right-click menu for the
reset command, so the reset-to-default function that was added in 6652
(git:0cd7476) was not accessible from eeschema.
* 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.
- When the Kicad manager is iconized, all other child frames are iconized (normal wxWidgets behavior)
- For viewer frames in modal mode, there is a more annoying issue: they have the wxFLOAT_ON_PARENT frame style on unix, and wxSTAY_ON_TOP on Windows.
wxFLOAT_ON_PARENT frame style is incorrect (although on most WM it works) because the parent frame (Kicad manager Frame) is not the caller. It is usually a main editor frame.
It does not work on Windows (wx STAY_ON_TOP is used).
* Now each editor frame has a null parent.
Therefore iconizing the Kicad manager frame does not iconize other frames.
* Viewer frames have null parent in normal mode and the caller parent in modal mode (therefore wxFLOAT_ON_PARENT frame style is always and correctly used)
* References to opened/closed main frames are no more managed by the (complicated) kicad code. Instead of, a non critical and more easy to understand code just uses FindWindowByName to know if a main window exists or not.
These changes do not fix all issues about Kicad frames brought to the foreground or the background, but it fixes a few issues, and AFAIK do not add other issues.
The functions involved in the problem were PGM_BASE::GetEditorName and
EDA_BASE_FRAME::OnSelectPreferredEditor:
1) OnSelectPreferredEditor showed a dialog to allow the user selecting the
editor, but before that called GetEditorName to get the name of the current
editor (to show as a default in the choose file dialog).
2) The problem was when there was no editor, GetEditorName showed its own
dialog.
3) So the user was seeing first the dialog from (2) and then the dialog from
(1).
4) As GetEditorName is used in many other places the solution I did was to add
to it an optional parameter that tells it what to do if no editor is set. To
avoid modifying other code that relies on the current behaviour, this parameter
has a default value that causes to show the dialog. But now when
OnSelectPreferredEditor calls it, it passes the parameter that causes it to
return an empty string if no editor was set.
5) Also, I found a second bug while doing it which allowed in the first dialog
to select an unexistent file (the dialog was missing the wxFD_FILE_MUST_EXIST
flag).
6) Lastly, to avoid having duplicated code (the one that showed the same dialog
and that configured the wildcard was in two methods) I created a single
function that now both functions call: PGM_BASE::AskUserForPreferredEditor.
This way we also will have consistency in the behaviour of both dialogs and
there is a single place where it needs to be modified.
I tried to merge some constants used both in legacy mode and gal mode (which were, before this patch, separate constants).
There is still a serious work to avoid different calculation code for the same text in draw and plot functions.
Work in progress to merge these calculation functions.
In the C++ standard, this function is only defined for floating point
types, and integers cannot be implicitly converted. Using explicit
conversions avoids a GCC specific extension to the standard library.
* Dick Hollenbeck also contributed commit r6440. I inadvertently forgot to set
the Bazaar author tag before I committed it. My apologies.
* Switch to static linking of libcurl and on linux and windows and also
statically link in only required portions of openssl.
* Add the required thread locks which openssl needs.
* Remove the get curl version call from BASEFRAME since it pulls in curl and
openssl into every derived wxFrame class link image.
* Remove curl function from PGM_BASE, switch to atexit() instead. Anything in
PGM_BASE made the singletops bigger.
* Tested on Linux, Windows, and OSX.
* Prevent libcurl from inadvertently being initialized twice.
* Dynamically load libcurl only when required.
* Reduce the number of worker threads when loading footprint libraries to
prevent issues with the GitHub plugin.
* Replace the wxListCtrl with a wxTreeListCtrl, allowing expandable categories
in a future change.
* Clean up the code to make HOTKEY_LIST_CTRL function a bit better on its own.
* Migrate the hotkey dialog to TransferData{To,From}Window, use matching
TransferData{To,From}Control methods on HOTKEY_LIST_CTRL so it is easy to
embed.
1. Fixed an assumption somebody originally made in the plugin that std::string had contiguous storage. This is not specced behavior pre C++11 so we gamble by calling .reserve() which should give a far better guarantee.
2. Added copy to clipboard information for curl
3. Removed some openssl references in compiling.md
4. Renamed struct vars to be uppercase to match "public var" code style policy
* Create base class EDA_PATTERN_MATCH to hand multiple pattern matching methods.
* Create classes for regular expression and wildcard pattern matching.
* Add new pattern matching semantics to component select dialog.
* Thanks to Henner Zellar <h.zeller@acm.org> for improvments to the original patch.
non-transformed S3DMODEL for rendering.
+ S3D_CACHE now caches S3DMODEL and returns a pointer to a single
instance of the S3DMODEL for repeated calls to Prepare()
+ Beginning the VRML Plugin
In polygon calculations (combining polygons, fracture) the mode of calculation (fast or strictly simple polygon option) as no more a default value, because choosing the best mode is better to optimize the calculation time.
'GetVersion'.
+ Introduced normal calculations. This is buggy due to multiple equal
face normals distorting the vertex normal; this will be fixed by
removing the redundant face normals from the calculations.
* Rename Eda_FileSelector to EDA_FILE_SELECTOR.
* Add optional pointer to wxString to save the most recently used path to EDA_FILE_SELECTOR.
* Rename Eda_DirectorySelector to EDA_PATH_SELECTOR.
* Replace wxGetCwd() with wxStandardPaths::GetDocumentsDir(). This fixes the windows issue
where wxGetCwd() returns the path where the executable files are located.
* Add code to handle most recently used path to EDA_BASE_FRAME.
* Fix string formatting error in kicad/files-io.cpp.
* Remove setting and restoring current working directory when launching GerbView. Setting the CWD
has no effect on the launched executable which starts with it's own CWD.
* Allow project path to be passed to GerbView when launched from KiCad.
* Note: this is a work in progress. Do not expect every path and/or file selection dialog to properly
update the most recently used path. The correct solution to this problem requires a much more
well though out solution which will not happen until after the next stable release.
* SearchHelpFileFullPath(): clean up platform specific path code, add executable path sans bin
directory on non-osx platforms, and move KICAD path variable to the beginning of the search
list.
* Minor search stack debug output improvements.
* Push center on zoom, use middle mouse button to pan, limit panning, and
pan while moving object settings from schematic editor to symbol library
editor and symbol library viewer child windows.
* Push center on zoom, use middle mouse button to pan, limit panning, and
pan while moving object settings from board editor to footprint library
editor and footprint library viewer child windows.
PAD_SHAPE_T and PAD_ATTR_T still have a double definition (new names and old names) to be sure python scripts are nor broken by the change.
PAD_DRILL_SHAPE_T does not have a double definition, because it is unlikely oblong holes are used in python scripts.
Double definitions will be removed in the (next) future.
Fix an issue when a .kicad_pcb file contains an incorrect fpid ( containing a '/ ' in footprint section ) . After saving the board the file was no more readable, due to a broken fpid saved in file
(can happens in old .kicad_pcb files, coming from the bzr 4022 stable version, and/or in files converted from an other EDA tool like altium)
Fix 2 very minor coverity warnings.
* Remove ENVIRONMENT_VARIABLE_CHAR_VALIDATOR::OnChar() because it was skipping
the filtering of the first character. Not sure what was going but this seemed to fix the issue.
* Added environment variable name test to DIALOG_ENV_VAR_CONFIG::TransferDataFromWindow
because apparently validators do not get called in wxGrids even whe the extend window style
wxWS_EX_VALIDATE_RECURSIVELY is set.
* Set the default button using wxFormBuilder since the OK button is not part of a wxStdDialogButtonSizer.
* Minor improvements to the HTML help dialog.
* Fix assertion when calling HTML help dialog. Apparently any dialog derived from DIALOG_SHIM must
have a KIWAY top level window as a parent.
In 3D viewer, this option can take a *very long* calculation time (minutes instead of seconds, or hangs) and they are now using aFastMode = true to do polygon calculations, especially for zones inside zones belong to the same net but having different priority (which creates weak polygons).
aFastMode = false is the default for other calculations (zone filling) as before.
* Adds a "Grid Reference Point" to the VRML export; this allows a user to specify the (X,Y) coordinate which will be the origin point on the output
* Adds a "Grid Reference Point" to the IDF export; this is similar in purpose to the corresponding VRML export feature.
* Replace module nomenclature with footprint for improved consistency.
* Replace abbreviations in control text.
* Replace exchange nomenclature with change.
* Add code to allow each editing window it's own undo/redo count.
* Add code to allow for infinite undo/redo when count is set to 0.
* Add edit control to all editing windows general options dialog for
user configuration of undo/redo count.
* Add code to save and restore undo/redo count for each editing window.
Also add PAD_SHAPE_<PADSHAPE> equiv to PAD_<PADSHAPE> and PAD_ATTRIB_PAD_<PADATTRIB> equiv to PAD_<PADATTRIB>
(<PADSHAPE> = ROUND, RECT... and <PADATTRIB> =SMD, CONN ... )
* Update cross-hair position when using mouse wheel to pan.
* Add ugly hack when mouse cursor enters canvas to force the cross-hair visibility counter
back to zero. There was a bug on Windows when using the middle mouse button to pan
and the user released the middle mouse button off of the canvas, the cross-hair would no
longer be displayed until the window was closed and reopened.
Now all are calculated using the top to bottom draw Y axis. This is perhaps not a good idea, but at least it will be easy to change, later.
Code cleaning relative to these bounding boxes.
* Remove global s_NetObjectslist.
* Separate out non-owning version of NETLIST_OBJECTS_LIST into NETLIST_OBJECTS.
* Fix double free pertaining to ~NETLIST_READER().
* Remove all file-io from CvPCB.
* Remove exe launcher cvpcb, retain only cvpcb.kiface, since cvpcb.kiface has no file i/o.
* Add void CVPCB_MAINFRAME::KiwayMailIn( KIWAY_EXPRESS& mail ) and teach it to use old
netlist loading code with a STRING_LINE_READER LINE_READER.
* Fix BEGIN_EVENT_TABLE( CVPCB_MAINFRAME, KIWAY_PLAYER )
* auto-save was broken for all sub sheets with are in a sub-directory of the project directory. (reason wxFileName::Normalize(), used to create the absolute path has issues with filenames starting by '$', perhaps due to env var which also start by $). the auto-save prefix is modified ( now AUTOSAVE_PREFIX_FILENAME which defines "_save_" ) and defined only once.
* auto-save files from sub-sheets were not found due to the fact the path was not set (fixed by Blair Bonnet's patch)
* Use only double to store zoom levels in class BASE_SCREEN (int type is not working for eeschema or page layout editor) (this fix Bug #1450551, Assertion failed on wxRound() when zooming)
* Fix crash in all apps but Pcbnew when a grid or a zoom was selected from the popup menu.
* Modify default hotkeys for Next Grid and Previous Grid: the initial key was a dead key, not suitable as hotkey. the 'N' and Shift N keys are used instead (with a change for unfill zone hotkey)
* Modify code in EDA_DRAW_FRAME::SetNextGrid() and EDA_DRAW_FRAME::SetPreviousGrid() to make them compatible with other editors than the board editor.
* Add code to test if any of the components in the schematic cache have been changed
in the component libraries.
* Prompt user to accept or reject components when changes are found.
* If the user chooses to use the components in the cache, create a new library with the old
components and add it to the beginning of the component library list so the schematic will
not be changed.
* Create dialogs to handle user feedback and status.
Previously, only the lib named "power" was used (and therefore power parts defined in other libs not shown).
Now, all power parts can be loaded from any library.
Also, when loading power parts from the chose component dialog or the lib viewer, libs and parts are filtered: only power parts and libs containing power parts are listed.
Hotkeys: move a few global strings in the files where ther are actually used (and make them local.) and code cleaning.
Fix a few other minor issues.
Modedit, GAL mode: fix a crash when a duplicated area includes the ref or value fields.
Add missing bitmap for pad enumerate.
fix bad flag for Portuguese language.
Fix a few typo in messages.
* Create new dialog to edit environment variables.
* Add helper class ENV_VAR_ITEM to manage environment variable values and
if they were defined externally.
* A path configuration dialog access to KiCad, CvPcb, Pcbnew, and Footprint Editor
window menus.
* Add validator for environment variables.
these options are used in GAL mode, but the usercannot control this visibility. So if the board file does not have these visibility flags set, the GAL never show them.
Fix also a compil warning.
legacy plugin: better compatibility with old brd files (current track width and current vias size, stored in SETUP section, were not read from file and incorrectly set)
Eeschema now uses dashed lines for graphic lines (to be consistent with plot functions and toolbal icon).
Fix an old bug in some envionments which warp the mouse on a bad monitor when opening eeschema, pcbnew and some other windows, only noticeable guys who are lucky enough to have more than one monitor.
- CACHED_CONTAINER::GetVertices: removed useless and unused function
which does nothing but tainted the API
- SHAPE_LINE_CHAIN::Collide( const BOX2I& aBox, int aClearance ):
removed an outdated function with assert(false)
- SHAPE::BBox(): fix a small typo in the doc string
* Fix default KISYSMOD/KISYS3DMOD (#ifdef typo) for OSX builds.
* Remove setting KIGITHUB from kicad/pcbnew Info.plist in favor of hardcoded default
setting for OSX builds.
* Remove now unneeded Set3DShapesDefaultPath() and other small things.
* 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
* Fix unitialized variable in MSG_PANEL_ITEM default ctor.
* Fix a bunch of uncaught exception issues.
* Fix a memory leak in the NETLIST_READER::GetNetlistReader() when an
an attempt to read an invalid net list file occurs.
Rename eeschema/dialogs/dialog_sch_find.fbp to dialog_schematic_find_base.fbp, to be consistent with other dialogs.
Pcbnew run from the project manager: add menu Save Copy As..., which is the same command as Save As ... in stand alone mode, but with the constraints of a project (no cwd change, no board filename change, and keep project settings)
Text arrays can now use "%s" as a placeholder to be substituted with the array index.
Also expand menu options for move exact, arrays and duplicate.
Minor fixes for arrays - use proper unit parsing, add numbering start for circular arrays
Add circle radius indicator to array dialogue
These settings are now not common to the board editor, because the footprint editor can be run outside the board editor.
download_boost.cmake: ignore .htm* files when installing boost. They are not used, and often have a very very long (and stupid) name which sometimes creates issues.
* Fix -Woverloaded-virtual warning in DIALOG_LIB_NEW_COMPONENT class
definition.
* Make EDA_ITEM::Matches( const wxString& wxFindReplaceData& ) protected
since it's a helper function that should only be called by derived objects.
* if the current select plugin is the github plugin, one can select some of these libraries and add them to the table
* if the current select plugin is the kicad plugin, one can select some of these libraries and download them to make alocal copy.
They can added to the table after they are downloaded.
this option was possible only by modifying the way display options are managed.
before these changes, display options were a global DISPLAY_OPTIONS class instance.
Now each EDA_DRAW_FRAME(and derivated classes) includes its own DISPLAY_OPTIONS class instance.
As a consequence, some duplicate display option variables in these classes have been removed, because there were just duplicate variables of the DISPLAY_OPTIONS class instance.
Please, note the layer manager was already available in GAL mode, but is was the same as tne board editor, which is not good.
Now:
- In default mode or GAL mode, the look is the same.
- Only suitable technical layers (i.e. paired layers) are selectable from the layers manager (for special purposes, some other layers can be used, via the graphic items properties dialog)
When the filename is not absolute, the page layout file is now searched first in project folder, and then in kicad template folder, if not found in project.
Fix issue when using a page layout file in project folder: eeschema and Pcbnew did not use it, unless using an absolute path.
Now, if the file path is nor absolute, it is seen as relative to the project (which is the expected behavior)
fp lib wizard: when pcbnew id compiled with USE_GITHUB_PLUGIN=OFF, the github plugin option is no more accessible (and the web viewer no more used).
Looked like a minor issue, but was due to a more serious bug, when using 2 different DSN_LEXERS which were not synchronized.
The fix is not perfect, but unfortunately, the parser used to read the PCB_PLOT_PARAMS in .kicad_pcb files is also used in legacy board file reader.
Therefore it is better than write 2 parser functions, one for legacy files, the other for the .kicad_pcb files, which make the same thing.
steps to better support devices with precise scrolling deltas (trackpads).
Scrolling is done in the handler rather than creating and firing cmd events.
This is intended to support two-finger scrolling on the Magic Trackpad.
- Added a preference, 'Use mousewheel to pan', to allow panning by default
on mousewheel events. This reverses the existing behavior where unmodified
mousewheel zooms and Shift/Cmd modified pans.
The old behavior was:
- Unmodified scrollwheel performed zoom in/out
- Shift modified scrollwheel performed pan up/down
- Cmd modified scrollwheel performed pan left/right
- Shift+Cmd modified scrollwheel performed zoom in/out
with no cursor warp
With the new preference checked, this changes to:
- Unmodified scrollwheel performs pan up/down
- Shift modified scrollwheel performs pan left/right
- Cmd modified scrollwheel performs zoom in/out
- Shift+Cmd modified scrollwheel performs zoom in/out
with no cursor warp
With the preference unchecked, this is now:
- Unmodified scrollwheel performed zoom in/out
- Shift modified scrollwheel performed pan left/right
- Cmd modified scrollwheel performed pan up/down
- Shift+Cmd modified scrollwheel performed zoom in/out
with no cursor warp
It should be noted that for the last case, the behavior has changed.
This is not arbitrary. This now matches expected behavior for an OS X
application. This also matches what wxWidgets expects on this platform
as wxWidgets changes the axis of mousewheel events to horizontal when
the event is shift-modified.
The preference is added everwhere that mouse preferences previously
existed, i.e., eeschema, pcbnew and gerbview. The 3D Viewer does
not yet honor this preference, but behaves as if it was checked.
The pl_editor does not currently have any preferences to honor.
As with the magnify event support, this covers canvases for all
current tools, EDA_DRAW_PANEL, EDA_3D_CANVAS and EDA_DRAW_PANEL_GAL.
This does NOT modify the behavior of mousewheel zooming, though it
probably should. This remains unsuitable for use with a trackpad,
use pinch-to-zoom instead.
Committing this separately from the rest to ease making a patch for just this
functionality in case that it might make it into the trunk.
This can function standalone, though it is less useful without the rest.
It requires that wxwidgets-3.0.0_macosx_magnify_event.patch be applied to wxWidgets
It is completely optional; everything is guarded by the USE_OSX_MAGNIFY_EVENT macro.
- Added OnMagnify event handler to EDA_DRAW_PANEL, EDA_3D_CANVAS and the helper for
EDA_DRAW_PANEL_GAL, WX_VIEW_CONTROLS. This should cover canvases all current tools.
- Guarded all with USE_OSX_MAGNIFY EVENT feature macro and added support in CMakeLists.txt
* Improve VRML export dialog lay out.
* Make the OK button the default action in the export dialog.
* Make 3D model export work correctly and avoid redundant file copies.
* Fix embedded path separators in wrl files on windows.
* Fix absolute model file path creation in wrl files.
* Clean up VRML export code.
* Change hot key editing contol from wxGridTableBase to wxListCtrl.
* Separate hot key lists into separate tabs rather than one large list.
* Coding policy fixes.
* Many path related fixes.
* Fix execution of external applications.
* Update mac-osx.txt.
* Add top-level links for standalone applications inside OSX bundle.
* Fix document icons for Eeschema and pl_editor.
* Create individual bundles for standalone applications inside the main application bundle.
* Add usual 'site-packages' to python path in OSX bundle.
* Fix name of OSX bundle plugin folder.
Rename "Switch highcontrast" to "Toggle High Contrast".
Eliminate most of the abbreviated hotkey titles.
Doxygenize dialog_hotkeys_editor.h and add missing license block.
Display <unassigned> if key code is 0 (NULL).
Refactor hotkey editor to use tab control instead of one giant list.
Each tab is a separate hotkey section.
Modify EDA_HOTKEY_CONFIG to change the m_Comment member to m_Title for a new purpose.
We want a pretty title in the hotkey editor. We use m_Title for the key export comment which
still conveys the purpose just as easily.
Refactored usage of wxGrid into wxListCtrl which allows capturing navigation characters
and also works better (single selection is built in).
Add hotkey overwrite prompts that are paired with "Common" section. It will check if a hotkey
overlaps with the proper sections. i.e. Common with the all other sections; or Section 1 with just Common.
Right-click menu removed due to wxListCtrl being able to catch the special keys properly.
* Compile all binaries into a single application bundle.
* Use CMake BundleUtilities to make application bundle relocatable.
* Restructure build output to directly create an image file.
* Fix default search paths.
* Set KIGITHUB environment variable.
* Added patch to fix wxWidgets so names for OSX.
Schematic component properties dialog: add 2 helper buttons to manage the chip name (name of the corresponding part in lib)
- a browse button to chose an other chip name
- a test button, to know if the part exists. If not existing, list the parts found when searching using a case insensitive comparison.
- Removed the friends MODULE and FOOTPRINT_EDIT_FRAME from TEXTE_MODULE
(as in the @todo comment)
- Refactored the Rotate/Flip/Mirror for text in modules into the
TEXTE_MODULE class itself (members RotateWithModule, FlipWithModule,
MirrorWithModule)
- New behaviour in coloring text on screen: reference and value still
take the color from the MOD_TEXT_FR_VISIBLE and MOD_TEXT_BK_VISIBLE
visibles; other text takes the color of the layer containing it
(except when hidden, obviously) but still get its visibility
controlled by those visibles (probably the most intuitive and useful
behaviour)
- Still need to decide: should text on a layer be hidden when the layer
is? Probably yes (still to be implemented);
- Some comment fixed and many cast converted to static_cast
* Create GetNewConfig() and GetKicadConfigPath() to unify configuration file
creation and location.
* Move Windows configuration out of the registry into configuration files.
* Move Linux configuration files from $HOME to $HOME/.config/kicad to eliminate
configuration file pollution in the users $HOME folder.
* Fix a bug in the configuration file where the Eeschema hot keys are saved.
* Add hot key handled return indicator to DRAW_FRAME::GeneralControl() and
DRAW_FRAME::OnHotKey() and all classed derived from DRAW_FRAME.
* Add code to all GeneralControl() and OnHotKey() functions to return true if
hot key was handled.
* Call event skip in DRAW_PANEL::OnKeyEvent() when key event is not handled to
allow default menu event handler to function properly.
* Fix Eeschema back annotation bug where footprint field visibility setting was ignored.
* Replace two confusing and ambiguous dialogs with a simple single choice dialog.
Ensure some values initialized by the schematic editor and used by libedit are also initialized in libedit even if the schematic editor was not started.
Remove useless commands (save/load project config) in libedit, because now they have no sense.
This fixes Bug #1360219 (Lost settings in eeschema) and keep separation between code relative to lib management and code relative to preferences.
2 or 3 minor settings could be lost in some designs, but they are very easy to reenter.
* Refresh canvas when user cancels edits so that the discarded sheet is
cleared from the schematic.
* Add file name validation to the sheet properties dialog to prevent
illegal file name characters from being entered into the text control.
* Rename FOOTPRINT_NAME_VALIDATOR to FILE_NAME_CHAR_VALIDATOR for clarity.
wxUpdateUIEvent events can be sent to parent frames, when opening a menu in a child frame, if parent and child frame share same ID fro menuitems (or tools)
The wrong menuitem can be used in some cases ( because there are more than one menuitem with the same identifier), by a wxUpdateUIEvent event function run in a parent frame.
*) 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.
Remove a minor warning message in Debug mode for 2 dialogs.
Pcbnew: update Gerber X2 file format (File Attribute) to very last X2 specification
Eeschema: Fix a minor bug in block selection (sometimes the last selected component was select instead of items in selected area)
and better drag behavior when draging an item by the drag hotkey.
