Zooming out does not update page background color to fit the width

First of all, thanks for the library. I really like the way you approach it and I have high hopes for its future development.

However, I encountered one issue with zooming. For some PDF documents, if you zoom out, the canvas isn't updated with the new dimensions for the page background.

I would appreciate if you can fix this. Thanks!
