When Running QtWebKit on top of directfb (qt-embedded 4.7.2)  I noticed that
the image decoding is very very slow
compared to WebKitGtk.
Some images are displayed in 3 secs compared to 0.3 secs.

http://nontroppo.org/timer for example took 2200ms on webKitGtk

however it needs more than 6000ms for the full load.

(the scores are collected on a ST SoC.)

I've found the following entry in the bugs.webkit.org
<https://bugs.webkit.org/show_bug.cgi?id=27538>but the work done by Holger
was not totally applied in QtWebKit
especially the patch to use the webcore image decoders . is there any reason
for that?

the patches are a bit old compared to the current code. Does any body have
an updated one applicable on the QtWebKit-2.2?

thanks for your help.
