Subject: [PATCH] Added InitMouseEvent helper method (like wxMSW) Implemented
 the following mouse handlers: mouseDown, mouseDragged, mouseUp, mouseMoved
 Added stubs for the following mouse handlers: mouseEntered, mouseExited,
 rightMouseDown, rightMouseDragged, rightMouseUp, otherMouseDown,
 otherMouseDragged, otherMouseUp
