Pinch zoom behavior on embedded PDFs

[Ayush Jindal]

Hey,

For embedded PDFs, pinch zooming on parent page seems to zoom the embedded PDF page without actually rendering/scaling it up properly at new zoom level.

I understand that it won't actually redraw the actual PDF content but even the text on the PDF toolbar is pixelated.

This doesn't happen with other OOPIF content like

http://csreis.github.io/tests/cross-site-iframe-simple.html

Here when you pinch zoom in, the text inside the iframe is initially blurry/pixelated but it eventually gets re-rendered when you're done with the gesture.

Can someone explain why is that and if it's possible to fix it for the embedded PDF case?

This may be an issue with MimeHandlerViewGuest or GuestViews in
general. It may be good to file a bug about this.
