Problem Description

OnPaint has always been sharing the OSR pictures using FrameSinkVideoCapturer, but via CPU. This is not optimal performance, and a GPU based OSR would be in favor instead of the current one.

CEF has OnAcceleratedPaint, but was dead since M103, however this PR reintroduced the capability since M125 (possibly backport to M124): https://bitbucket.org/chromiumembedded/cef/pull-requests/734

I think electron fundamentally use same arch as CEF does, and I think we can also port this to electron.

A PR will follow shortly.
