support accelerated compositing?

[qifuren1985]

chrome has support accelerated compositing, it can support 3d css. So how about to support accelerated compositing?

in cef_context.cc,if we set "webprefs_->accelerated_compositing_enabled = true;", cef will crashed when we open the page that contain 3d css.

Does it work in the test_shell application at the Chromium HEAD revision? If so, it will probably work in CEF after the next update.

in chrome head version,it I used "chrome.exe --enable-accelerated-compositing" to run the page http://webkit.org/blog-files/3d-transfo ... ircle.html , it works OK. But in test_shell.exe, it doesn't work.

it 3d css works,it looks like below:

It seems that cef doesn't support html5 feathers( http://html5demos.com/ ).

The first step is to get support for these features added to test_shell in the Chromium HEAD revision. Once the features exist in test_shell they'll be picked up by the next CEF update.

Revision 128 supports accelerated compositing for 3D CSS transforms.

It speeds lot's CPU(45%),but chrome.exe only spends 10% CPU.

I test with cef_binary_r195_VS2008, when I run examples with accelerated compositing, it uses lot's of cpu.it seems cefclient use CPU accelerated compositing, not GPU accelerated compositing.

Try changing the value of the SetTimer() call in cefclient -- that will probably have an effect.
