This method captures all application/pdf streams, loads the viewer
and passes the stream to the PDF.js viewer.
This commit shows a proof of concept using the chrome.streamsPrivate API.
Advantages of new method:
- Access to the response body of the original request, thus fewer
network requests.
- PDFs from non-GET requests (e.g. POST) are now supported.
- FTP files are also supported.
Possible improvements:
- Use declared content scripts instead of dynamic chrome.tabs.executeScript.
This allows the extension to render the viewer in frames when the
extension is disallowed to run executeScript for the top URL.
- Use chrome.declarativeWebRequest instead of webRequest, and replace
background page with event page (don't forget to profile the
difference & will the background/event page still work as intended?).
