[Texmacs-dev] preliminary HiDPI (Retina) support for TeXmacs/Qt

Hi all,
 I've committed a series of preparatory patches to support HiDPI displays 
(Retina) on Qt/Mac. 

For some reasons I didn't had time to prepare a well packaged commit  to fully 
support Retina to the svn trunk so I attach here a patch to be applied to the 
current svn (r5963) to enable *unconditionally* **partial*** Retina support. 

Unconditional  means that the double resolution is hardcoded and TeXmacs will 
not try to check if the screen is really Retina or not. Of course I will work 
later on this issue and prepare something better. But for the moment this patch 
will allow those like me who have a Retina MacBookPro to work with TeXmacs 
without headache.

At the moment this support cannot be fully completed since Qt (4.8.4) cannot 
handle properly HiDPI bitmaps so the icons  in the menus are bounded to be at 
low resolution. However the editing area can be rendered at HiDPI. 

I only have checked that it works with the latest Qt 4.8.4. I'm not sure 
previous versions have any kind of HiDPI support. 

By the way,  TeXmacs typesetting on Retina looks gorgeous.
