[webkit-qt] Reproducing buildbot layout test results

[Andreas Kling]

Hey QtWebKittens!

I'm trying to convince my machine to produce the same layout test 
results as the bot(s) in Szeged, in order to do some large-scale 
rebaselining without using the bots as a middle man.

So far I've got:

* 32-bit Ubuntu machine (VMWare)
* Qt 4.6.2
* WebKit trunk

Switching to 32-bit helped some, but rendering metrics still differ all 
over the place, so I'm not quite there yet.

Could someone tell me a bit more about the environment the bots are 
running? (Or if you immediately know what I'm missing, just tell me that 
;-))

Random theories for your consideration/amusement:
* I need some specific fonts (other than the $WEBKIT_TESTFONTS.)
* I need some specific font settings.
* I need some specific Qt style.
