cocos2dx win32修改鼠标指针图案

win32的api实在太麻烦了，但是glView里面有个setCursorVisible的方法，可是借此实现同样的效果。

AppDelegate.cpp中：

glview = GLViewImpl::createWithFullScreen("123465");
glview->setCursorVisible(false);
director->setopenGLView(glview);

自己的layer中：

//鼠标指针
auto cursor = Sprite::create("cursor_nor.png");
this->_cursor = Node::create();
this->_cursor->addChild(cursor);
this->addChild(this->_cursor,10000);

auto listenerMouse = EventListenerMouse::create();
    listenerMouse->onMouseMove = [&](cocos2d::EventMouse* event) {
        Point mouse = event->getLocation();
        mouse.y = 1024 - mouse.y;

        this->_cursor->setPosition(Point(mouse.x+20,mouse.y-30));
    };
    listenerMouse->onMouseDown = [&](cocos2d::EventMouse* event) {
        this->_cursor->removeAllChildren();
        auto cursor = Sprite::create("cursor_pre.png");
        this->_cursor->addChild(cursor);
    };
    listenerMouse->onmouseup = [&](cocos2d::EventMouse* event) {
        this->_cursor->removeAllChildren();
        auto cursor = Sprite::create("cursor_nor.png");
        this->_cursor->addChild(cursor);
    };
    this->_eventdispatcher->addEventListenerWithFixedPriority(listenerMouse,1);
