`return fullscreened_tab_ != NULL;` please

Also, I don't understand from the function name what this does.

(I looked at the comment for fullscreened_tab_ and didn't understand that
either. Is that the tab that was current when fullscreen was entered? Or the one
that's active when fullscreen is left? Or something else? What's this needed
for, why not a notification?)

Done.
This is true when the current tab is in fullscreen mode as requested by
webkitRequestFullScreen. There can only be one such tab per browser window at a
time.

This is needed so we can avoid showing the bubble UI when entering FS mode as a
result of the user clicking the menu item ("Enter Presentation Mode"). I gather
from bug http://code.google.com/p/chromium/issues/detail?id=14471#c21 that this
is the desired behaviour.
