original cef will create child window to display web pages.so if you want embedded web in a windowless system(like 3D game).it's uesless.
I have been add some code for cef to support windowless mode.
1 .in windowless mode.you will be notice with a invalidate Rectangle by handler when web page need redraw(include scroll and composite).
2. and then you can Paint webview to your specify Device Context.and
3. and then you can display it in any place you want(exp. in 3D scene,blend it on the desktop with alpha)
but. I have no idea about whether my modification is appropriately.
first,my modification is stick on Windows cause I don't have experienced on cross-platform coding.
second,I change some code remark with don' edit by hand.
any guide or tutorial about contribute code for the project or I can just send code to project administrator?
