and therefore tracks are now dragged when a end point is inside a pad, not necessary on the pad position.
However, drag functions still need more cleanup.
* 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.
* Make EDA_DRAW_FRAME current tool ID member variable private.
* Added global no tool selected ID to replace application specific no
tool selected IDs.
* Change SetToolID to prevent setting the tool ID to anything less than
the new global no tool selected ID and assert on debug builds.
* Change command and update user interface command event handlers to use
new global no tool selected ID.
* Fixed schematic library editor add pin hot key handler.
* Old control state handling code completely removed in all applications.
* Factor common control state handlers into EDA_DRAW_FRAME.
* Replaced EDA_ITEM test for newness with IsNew() method.
* Factor vertical right toolbar command handlers out of giant edit command
switch statement in EESchema and PCBNew.
* Rename all member variables and methods that reference the cross hair
code in draw panel object from cursor to cross hair to eliminate confusion
between the two concepts.
* Rename cursor capture call backs in draw panel object to improve code
readability.
* Create helper class for turning off the cross hair while drawing.
* Remove redundant block clear code.
* Remove redundant mouse capture call back reset code when end capture
call back is called.
* Remove unused function definitions in base draw frame object.
* Lots of minor coding policy and doxygen comment fixes.
* Remove all occurrences if #ifdef USE_WX_ZOOM and all associated code within
the #else/#endif block ( old zoom code ).
* Removed the build option for USE_WX_ZOOM from CMakeList.txt and config.h.in.
* Removed all scaling code in base screen object.
* Fixed buffered paint and buffered client DC on Windows. Buffering works
properly on Linux and Windows.
* Modified kicad_device_context.h to automatically uses buffering on platforms
where double buffering is supported natively.
* Remove all of the scaled versions of the drawing functions in gr_basic.cpp
and any support code.
* Removed all traces of ActiveScreen global variable from eeschema and
gerbview.
* Renamed Recadre_Trace to RedrawScreen in draw frame object.
* Renamed PostDirtyRect to RefreshDrawingRect in draw panel object.
* Lots of code cleaning an Doxygen comment improvements.
* Split out application specific command IDs to prevent unnecessary rebuilding.
* Eliminate duplicate menu and tool bar command IDs.
* Split component library editor and viewer definitions to separate header files.
* More component library and document file merge code.
* A bunch of minor string readability and consistency fixes.
