[texworks] Updated builds of TeXworks for OS X

[Stefan Löffler]

Hi,

thanks for your description of building universal binaries. I think,
things are beginning to add up in my head ;).

Doesn't qt.rb have a "universal" flag? From its formula:
['--universal', "Build both x86_64 and x86 architectures."]

It doesn't seem to build ppc binaries, though. Anyway, I could imagine
that patches for this might also be of interest to the upstream repo...

Thanks. I'll see if I can wrap something up, but I'm not going to have
much time in the foreseeable future. So if someone else has a go at it I
wouldn't mind ;).

Hm...
You could try to see what QImageReader::supportedImageFormats() gives
(you'll also need to add "#include <QImageReader>"; see
http://doc.trolltech.com/4.7/qimagereader.html#supportedImageFormats) at
run time.

Other than that, I found
http://doc.trolltech.com/4.7/deployment-mac.html#the-mac-deployment-tool, which
states (among other things) that Qt's default deployment tool follows
the "Image format plugins are always deployed" policy. If CMake is not
using said macdeployqt, I guess you have to convince it to deploy those
image format plugins itself...
