使用c99 的％z修饰符，，如果不使用％zd 请使用％u

HISI_HWC gpu compose for layer cropHeight =-1,cropWidth =-1

实际是一个阴影的动画
applyDim

其实就是初始化的值
void Rect::makeInvalid() {
left = 0;
top = 0;
right = -1;
bottom = -1;
}

结果是这个样子

size有点奇怪

应该是这里搞得事情

trace是下面这个样子

下面这里设置size的，没有看到裁剪

applydim的流程如下

这里开始的dim

应该就是dimlayer了。

看看他的透明度时怎么设置下去的。

加到framecallback去播放动画的。

这个时hardware层
