Presentation Mode - Replaces #1388

[saebekassebil]

Replacing #1388 with this take from scratch which works quite a lot better (probably due to all the contributions to the rendering code since last try.

This PR is essentially the same, with the same changes:

• Presentation mode, means navigation per page - "Single Page Mode"
• <spacebar> has been added as a "Next Page" key
• A button has been added to the toolbar (But needs a fancy icon like the others).

Here, both Chrome and Firefox works pretty well with this solution, except a minor difference between the two of them: Firefox seems to handle padding and margin differently when using scrollIntoView - Therefore there is a minor visual difference. Firefox has no "padding" at the top of the window, when using fullscreen mode.

As last time: Fixes/Closes #1355 and #1083

Thank you for doing that.

There is a strange artifact on the last page: previous page is partially visible.

A few notes/question:

1. scroll bar is visible -- is it possible to hide make it semi-transparent it using CSS?
2. tabindex has to be adjusted for the following buttons;
3. add <span data-l10n-id="open_file_label" and string entries for the en-US locale files;
4. in CSS, you can refer non-existent PNG icon file (or you can draw something yourself) -- icon will be landed separate from this pull later.

Awesome! +1 from me

@brendandahl , could you take a peek as well?

[gigaherz]

Nice. Any chance at being able to scroll pages with the mouse wheel? Maybe in a followup update?

Also, not sure if it's pdf.js or firefox, but it's VERY slow (~5 seconds) when switching to/from fullscreen here (Firefox 14 in Windows XP).

Nice work regardless.

[saebekassebil]

@gigaherz Thanks. The mouse wheel stuff wouldn't be exactly what I've been aiming at, since this is more of a "presentation" mode / single page mode than a mere "fullscreen" mode. The reason for this is, that if you want to use the mouse wheel, you'll probably not be presenting anything, thus F11 / manual fullscreen migth be better suited?

Sounds weird about the slowness. Here it only take half a second or something like that. I don't think it's the implementation as it's super simple, and only calls the respective vendor provided methods for requesting fullscreen (document.mozRequestFullScreen)

[brendandahl]

Works very nicely here. Thanks Jakob!
