Attached is a small patch to get the DFB compilation going (against r40351)
and apart from this patch,
we need to add support code for DFB for the plugin's view
So see all the checks with "#if PLATFORM(X11)" in
WebCore/plugins/gtk/PluginViewGtk.cpp
and do the necessary stuff for DFB.
NOTE: The Xembed and XtBin will not work for DFB
Also i still need to figure out how to send DFBEvents to the plugin ?
