Review request for Okular.


Repository: okular


Description
-------

This patch adds a new configuration option to the pdf backend options: the user can select between the poppler Splash or Arthur backends.  Of course Splash is the default, but it's nice to have the choice -- I use it to debug Arthur.

I need some help, though (still Qt newbie).  With the current patch, backend changes do not go into effect until the document is reloaded. How do I make it go into effect when 'Ok' is clicked?  I suppose there's some signal that gets emitted, but what's its name?

Also, It'd be good to add a 'here be dragons' tooltip to the Arthur choice.  Is that possible?
