* 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.
*) 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.
2) LIB_RECTANGLE and related classes sscanf data read from a file using "%s"
without field limits, which can cause problems with malformed/really long
inputs.
3) If some of the optional fields in a lib line are missing, "tmp" can remain
uninitialized.
common.cpp: remove useless warning on wxWidgets < 3.0 about --with-gtkprint build option: on wxWidgets < 3.0 on Linux the print function does not work even with this build option.
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.
Event handlers are (dis)connected depending on the active view.
TOOL_DISPATCHER inherits from wxEvtHandler, so now it receives events directly instead of being fed by external handlers.
