Always rounding of unzooming coordinate values had caused
display glitch (e.g. black line on top edge in zooming).
JIRA issue: CORE-19466
- Add bRound parameter to UnZoomed function. If bRound is
TRUE, then do round by kernel32!MulDiv function.
Otherwise don't round.
- Add bRound parameter to CCanvasWindow::CanvasToImage.
- Make bRound = FALSE default.
- Use bRound = TRUE for CCanvasWindow::OnButtonDown,
CCanvasWindow::OnButtonDblClk,
CCanvasWindow::OnMouseMove, and CCanvasWindow::OnButtonUp.
