Feature Request - Add support for direct DevTools protocol messaging

[amaitland]

CEF has added support for Direct DevTools protocol messaging.

See https://bitbucket.org/chromiumembedded/cef/issues/2961/add-support-for-direct-communication-over

• Add IBrowserHost.SendDevToolsMessage
• Add IBrowserHost.ExecuteDevToolsMethod
• Add IBrowserHost.AddDevToolsMessageObserver

[amaitland]

In theory this should open up a lot of different possabilities

• Network.clearBrowserCache to clear the cache at runtime.
• Clearing of localStorage
• Screenshots

[amaitland]

Added to master in commit 49ee249

[amaitland]

An example of taking a screenshot is available see eee134c

[amaitland]

IBrowserHost.ExecuteDevToolsMethodAsync has been added to allow for execution without having to marshal the call onto the CEF UI thread.

These changes have now been merged into the cefsharp/83 branch.

I'll look at adding a nicer API on top of the CEF API as a subsequent issue.

Are there any way to target the DevTools Protocol Event ? I want to count the amount of data transferred over network . but nothing can target the Devtool Protocol Network Event in https://chromedevtools.github.io/devtools-protocol/1-3/Network/

I have use the cefsharp example of DevToolsExtensions.CaptureScreenShotAsPng
