* Remove most (not all) variables that were initialized but never used that
cause GCC 4.6 to generate a warning.
* Fix bug in schematic library editor best zoom calculation.
Pcbnew: refresh issue with dialog designe rules under wxWidgets 2.9.2 under WINDOWS (replace wxChoiceBox by wxComboBox, should not change anything for users)
Eeschema: some issues in libedit (when editing a pin )
* Change class WinEDA_MsgPanel name to EDA_MSG_PANEL per coding policy.
* Change some old set message panel code in PCBNew with updated message
panel methods in EDA_DRAW_FRAME.
* Remove unused global function Affiche_1_Parametre.
* Minor Doxygen warning fixes.
In Render, colors shown were the default colors, not the selected colors, when starting Pcbnew or Gerbview,
because colors were not updated after reading the config.
* Move undo item copy global variable into schematic editor frame object
member variable.
* Add helper methods for accessing the undo item copy member variable.
* Fix undetected bug when changing a text type.
* Added an exchange command to the undo/redo base class for handling undoing
a changed item type which cannot be undone by swapping out the variables.
* Revert change to common/hotkeys_basic.cpp that broke hot key behavior.
* Lots of coding policy changes while making the changes above.
(WxWidgets 2.9.1 seems call setlocale( LC_NUMERIC, "" ) when wxConfig read doubles stored in config, but forget to back to current locale.)
Note: perhaps there are some dialogs that need this call to SetLocaleTo_Default() ).
* Minor code cleanup in pcbnew/netlist.cpp
* Set default button on all dialogs that do not already have a defined
default button. The only exception is the EESchema net list dialog
which needs converted over to wxFormBuilder and due to it's design makes
setting the default button in any tab other than the default tab
problematic.
* Fix escape key dialog handling bug in EESchema print post script
dialog.
* Remove clearance and net class name read only text boxes from PCBNew
auxiliary tool bar.
* Display full net class information in message panel when an object that
supports net classes is selected.
* Move coordinate string conversion function to EDA_DRAW_FRAME object and
made it more versatile.
* Refresh message panel text when units change.
