[webkit-help] ACCELERATED_COMPOSITING #define in FrameView.cpp

Currently, you cannot (apart from hacking the value of
WTF_USE_ACCELERATED_COMPOSITING in Platform.h or the build system).

The default value depends on the platform as it needs some support
from the underlying graphic library as well as some WebKit platform
dependent code. It is currently implemented for Mac but Chromium has
taken a first step.

Gtk does not have support for it yet.
