- Fix Undo/Redo mechanism. - Finish drawing when the tool is to be chanaged and when the file is to be saved. - Add ToolBase::OnFinishDraw to virtualize finishing drawing. - Extend bClearRedo parameter to ImageModel::Undo. - Add ImageModel::DrawSelectionBackground and ImageModel::DeleteSelection methods. - Fix some WM_PAINT message handling.
