This patch:
- Passes in a reference to the current PDFThumbnailViewer, which is used to ensure that the current thumbnail becomes visible when exiting PresentationMode.
- Changes the way that the event listeners for the contextmenu items are defined, to avoid passing in a reference to the SecondaryToolbar.
- Ensures that |supportsFullscreen| always returns a boolean.
Currently `supportsFullscreen` will, when the browser supports the fullscreen API, return e.g. `function mozRequestFullScreen()` instead of `true`.
- Simplifies the |click| handler code when PresentationMode is active.
This code has been obsolete ever since PR 2919 landed.
- Removes hack used to workaround a bug in WebKit browsers, which caused |mousemove| events to be fired when the cursor changed.
This was fixed close to a year ago, see http://code.google.com/p/chromium/issues/detail?id=103041.
This patch:
- Adds a couple of utility methods to `PDFViewer` to enable checking `presentationModeState` without cumbersome comparisons.
- Disentangles `PresentationMode` from `PDFHistory` and `HandTool`, by adding event listeners for `presentationmodechanged` to both of them.
- Adds a utility function to `PDFViewerApplication` for requesting PresentationMode.
- Prevents initialization of `PresentationMode` if the browser does not support the fullscreen API.
After the refactoring in PR 5678, the B2G viewer now prints the following in the console:
```
ReferenceError: DownloadManager is not defined
```
This will obviously not matter once the B2G viewer is replaced with the new components-based one. But until that happens, I think it makes sense to just stub the class to suppress the error.
For consistency, this preference should be placed amongst the others. The current position is purely for "historical" reasons, since it was one of the first preferences that was added to the code.
This patch also rearrange the order of the references to the DOM elements of the predefined zoom values, in viewer.js, to correspond with the element order in the current viewer UI. (The previous ordering is a leftover from the previous viewer UI.)
Instead of trying to hack around various browser defects, let's just disable PresentationMode in the affected browsers. This patch:
- Disables PresentationMode in IE11+ when the viewer is embedded; fixes 4711.
From reading IRC scrollback, it became clear that having to manually call `PDFFindController.resolveFirstPage` in order for the find functionality to work isn't particulary good. Hence this PR, which moves that code into `PDFViewer.setDocument` to make life easier for third-party implementations.
We can pass it in using the options object. Note that that this also avoids creating a DownloadManager object for each separate link (instead, having only one is enough).
Currently if you manage to e.g. open the console (with <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>K</kbd>) before the viewer is initialized, the following will be printed in the console: `TypeError: pdfViewer is null`.
This doesn't cause any actual errors, but nevertheless it seems like something we should avoid.
Followup to PR 5413.
Since `preferenceSidebarViewOnLoad` is an enumeration value, it seems better to initialize it with the default one instead of a boolean.
`preferencesPdfBugEnabled` uses a superfluous "s", which is a typo I made when I introduced it.
