++PCBNew * 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()
