Here we avoid copying and clearing pixels that will not be used in the whole tool loop process. Changes: * Add several member functions in ToolLoop to validate/invalidate regions of source/destination images so we know what regions are safe to use by inks and can be shown in the editor * Add new DocumentObserver::onExposeSpritePixels() member to validate pixels that will be displayed in the editor * Add Ink::needs/createSpecialSourceArea() member functions to validate extra areas for inks like blur or jumble * Add undoers::ModifiedRegion to save the undo information about the modified region * Add ShowHideDrawingCursor class * Change "blur" tool policy from overlap to accumulate (This is a real fix for issue #239)
