SkPicture 有多强大？

在 Skia 中，如果我将某些内容记录到 SkPicture 中，是否保证保留所有必要的内存？即

picture_canvas = picture.beginRecording(width, height);
picture_canvas->drawBitmap(*some_bitmap, 0, 0);
delete some_bitmap;
picture.endRecording();
some_canvas.drawPicture(picture); // will this crash since I deleted some_bitmap?

是否有任何情况下我可以删除导致drawPicture()崩溃的东西，或者它总是保证工作？

In Skia, if I record something into an SkPicture, is all necessary memory guaranteed to be preserved? i.e.

picture_canvas = picture.beginRecording(width, height);
picture_canvas->drawBitmap(*some_bitmap, 0, 0);
delete some_bitmap;
picture.endRecording();
some_canvas.drawPicture(picture); // will this crash since I deleted some_bitmap?

Is there any scenario where I could delete something that causes drawPicture() to crash, or is it always guaranteed to work?
