* Fix rendering bug in GerbView caused by wxDC scaling change caused by
setting the wxDC clipping region.
* Eliminate the need to have optional background erasing as the change
above fixed that problem as well.
* Default cursor handling improvements.
* Changed managed cursor callback definition to include the current
cursor drawing position.
* Modified all managed cursor callbacks to match new definition.
* Added snap to grid option to base drawing frame object.
* Changed add no connect managed cursor callback to use new position
parameter instead of the stored one.
* Lots of coding policy 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.
* Move schematic wire and bus break code into schematic screen object.
* Move schematic test for dangling ends into schematic screen object.
* Remove left over debugging output in schematic screen object.
* Remove unused file eeschema/cleanup.cpp.
* Fix bug in schematic line object hit test algorithm.
* Fix a string concatenation compile error added in r2752.
* Rename class WinEDA_BasicFrame to EDA_BASE_FRAME.
* Rename class WinEDA_DrawFrame to EDA_DRAW_FRAME.
* Rename class WinEDA_DrawPanel to EDA_DRAW_PANEL.
Added: in file dialog, multiple file selection.
Added: Draw mode selector (in left toolbar):
Raw mode:
a Gerber image is drawn on screen without buffering.
Artifacts happen if there are negative items drawn, if more than one Gerber file is shown.
Stacked mode:
each Geber image is drawn in a buffer and after drawn on screen
No artifact with negative items.
Each Gerber image covers previous images.
OR mode (transparency mode):
each Geber image is drawn in a buffer and after drawn on screen
No artifact with negative items.
Each Gerber image is "ORed" with previous images, like in Pcbnew.
Try to optimize Draw function in buffered modes.
(Useful for PC that have problems with "blit" graphic function)
Fix minor issues.
