* Modify algorithm to correctly calculate the virtual drawing size and
offset required to place the drawing correctly under all conditions.
* Ignore default wxWidgets scroll keys on Windows in EDA_DRAW_PANEL key
event handler.
Lee algorithm replaced by a Minimun Spanning Tree algo (using Prim's algorithm ).
Tested on a 5350 pads board, it is more than 100 times faster.
Also fix a crash when clicking on tool "delete selected items" (main horizontal toolbar),
and remove this tool (currently, no code in Pcbnew for this tool)
More about code refactoring in connect.cpp: RecalculateAllTracksNetcode() is 50 times faster with a board using 27000 tracks
Use right icon in pcbnew for load board and new board.
* Create command event handler for orienting schematic items and block.
* Remove redundant orient item and block command handler code and IDs.
* Remove redundant cancel current command event table entry.
* Remove unnecessary schematic bitmap object virtual functions.
* Set path when saving schematic sheet files to prevent assertion in
updated path and file write permission test function.
* Restore directory and file name write permission test function to it's
previous behavior to prevent unexpected save results.
* Add an assertion to verify the path is not empty to directory and file
write permission test function.
* Improve documentation for path and file write permission test function.
* Fix Doxygen link warnings.
* Change edit pin per part flag to only have effect when editing
component with multiple parts or alternate body styles.
* Move global edit pin pert part variable into library editor frame
object.
* Note that this only fixes the bug when the component does not have
multiple parts or alternate body styles.
* Create command event handler for draggining all schematic items.
* Remove redundant delete item command handler code.
* Remove unused close current tool command ID from process special
functions event handler.
* Add a rotate event handler to schematic frame object.
* Remove unique rotate item command IDs.
* Use process event instead of post event to eliminate the need to clean
up the command event client object from the heap.
* Unify find next item and next DRC error hot key commands.
* Unify move and rotate hot keys commands.
* Remove external dependency for adding suffix to reference designator
fields.
* Make schematic field get and set position methods transform coordinates
relative to the parent component object that owns them.
* Make base text class get text method virtual so derived classes can
change the base string according to their individual requirements.
* Fix a problem with default place schematic item add in last commit.
* Tweak move item to support moving schematic sheet pin objects.
* Change schematic sheet pin set position to constrain position within
the parent sheet.
* Schematic sheet pin moving now handled by unified move code.
* Remove old schematic sheet pin move code.
* Add custom client data object for passing hot key information to
command event handlers.
* Fix a bug that prevented changes to schematic sheet pin objects from
being undone.
* symbol in sch library have only single footprint filter,
* footprint filter have no wildcards,
* according footprint exists in pcb lib.
This could remove need in long equ files for lots of ICs.
* Fix a set position method bug in schematic item that caused the fields
to drawn in the wrong position.
* Group zoom hot keys to use the same command event in schematic and
library editor frames.
* Add get and set position methods to all schematic items.
* Encapsulate schematic item position members.
* Add swap data method to schematic items that lacked one.
* Remove global swap data function used by undo and redo functions.
* Unify as many schematic move methods as possible.
* Remove unnecessary place schematic item methods.
* All schematic items are now moved in the same event handler.
* Fixed bug in hierarchical sheet get menu item string method.
* Make no connect and junction items movable, fixes lp:804048
* Fixed bug on Windows that prevented the menu short cuts from working
properly.
* Fix duplicate menu short cut keys in KiCad, Pcbnew, and Eeschema.
* Add menu short cuts for all possible menu entries.
* Grammar and spelling fixes in Eeschema, CvPcb, and Pcbnew path and
library dialog tool tips.
* Translate the French file name subrill.cpp to highlight.cpp.
* Lots of coding style policy fixes.
