* Improved some comments on new functions.
* Improved some comments on new functions dirty area functions
* Changed
void ConvertPcbUnitsToPixelsUnits( EDA_Rect& aRect ); to
void ConvertPcbUnitsToPixelsUnits( EDA_Rect* aRect );
@ -21,6 +21,9 @@ email address.
* Changed from "new wxDCClip()" to use an automatic wxDCClip() variable in
drawpanel.cpp
* Removed a printf() from "release" build of drawpanel.cpp
* Added WinEDA_DrawPanel::PostDirtyRect()
* Renamed Supprime_Une_Piste() to Remove_One_Track() and it now uses
PostDirtyRect().
