A DESCRIPTION OF THE REQUEST :
The current "javax.swing.SwingUtilities.isLeftMouseButton" method is implemented as below:

    public static boolean isLeftMouseButton(MouseEvent anEvent) {
         return ((anEvent.getModifiers() & InputEvent.BUTTON1_MASK) != 0);
    }

Proposed "MouseEvent/isLeftButton" method:

    public boolean isLeftButton() {
         return ((getModifiers() & BUTTON1_MASK) != 0);
    }


JUSTIFICATION :
- "MouseEvent/isLeftButton" is more convenient than SwingUtilities.isLeftMouseButton
- e.isLeftButton() is more natural than SwingUtilities.isLeftMouseButton(e)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
CODE:
if (e.isLeftButton())...
ACTUAL -
CODE:
import javax.swing.SwingUtilities;
...
if (SwingUtilities.isLeftMouseButton(e))...
