* Removed Pcb_Frame argument from BOARD() constructor, since it precludes
having a BOARD being edited by more than one editor, it was a bad design.
And this meant removing m_PcbFrame from BOARD.
* removed BOARD::SetWindowFrame(), and BOARD::m_PcbFrame
* Removed the global BOARD_DESIGN_SETTINGS which was in class_board.cpp
* added BOARD_DESIGN_SETTINGS to the BOARD class, a full instance
* a couple dialogs now only change BOARD_DESIGN_SETTINGS when OK is pressed,
such as dialog_mask_clearance, dialog_drc, etc.
* Removed common/pcbcommon.cpp's int g_CurrentVersionPCB = 1 and replaced it
with build_version.h's #define BOARD_FILE_VERSION, although there may be a
better place for this constant.
* Made the public functions in PARAM_CFG_ARRAY be type const.
void SaveParam(..) const and void ReadParam(..) const
* PARAM_CFG_BASE now has virtual destructor since we have various way of
destroying the derived class and boost::ptr_vector must be told about this.
* Pass const PARAM_CFG_ARRAY& instead of PARAM_CFG_ARRAY so that we can use
an automatic PARAM_CFG_ARRAY which is on the stack.\
* PCB_EDIT_FRAME::GetProjectFileParameters() may no longer cache the array,
since it has to access the current BOARD and the BOARD can change.
Remember BOARD_DESIGN_SETTINGS are now in the BOARD.
* Made the m_BoundingBox member private, this was a brutally hard task,
and indicative of the lack of commitment to accessors and object oriented
design on the part of KiCad developers. We must do better.
Added BOARD::GetBoundingBox, SetBoundingBox(), ComputeBoundingBox().
* Added PCB_BASE_FRAME::GetBoardBoundingBox() which calls BOARD::ComputeBoundingBox()
* Fix grid select box update bug on context menu.
* Fix via size and track width select box update bugs.
* Fix layer pair indicator button update bug.
* Fix auto track width tool bar control enable bug.
* Fix via size and track width select status bug in context menu.
* Fix layer select box and layer control widget select bug when current
layer is removed.
* Add virtual function to notify objects derived from EDA_DRAW_FRAME that
the units setting has changed.
* Coding policy class naming fixes.
