Bug 71163 – --webkit-visual-word enable it in cr-win by command line flag

• Component: HTML Editing
• Status: RESOLVED FIXED

[Xiaomei Ji]

To minimize the risk to LTR users, we are thinking to enable this feature first to chromium win by command line flag.

And we can also short-cut in the code that for LTR text in LTR context, fallback to logical word movement (which is the same order as visual order).

The corresponding chromium side change is at: 
http://codereview.chromium.org/8400078/

workflow:
1. add command line flag --use-visual-word-movement, pass it from browser to renderer, and set m_visualWordMovement (newly added data member in WebViewImpl) to true when the flag is passed-in;
2. in EditorClientImpl, when webview's m_visualWordMovement is true, reset the mapping of ctrl-arrow from "MoveWordLeft/Right" to "MoveWordLeft/RightVisually" which are 2 newly added editing commands in EditorCommand.cpp

[Xiaomei Ji]

This and the corresponding chromium side CL are temporary, and they should be removed after the feature is enabled without command line flag.

this feels a lot like a per-Page setting.  shouldn't this be in WebSettings?

This should just be a run-time flag and should be done by WebSettings as Darin pointed out.

Thanks for the suggestion!
It is a per-page setting, and I set it through WebKit::WebSettings (not in WebCore::Settings to minimize the change in WebCore).

I'm probably not the best reviewer for the EditorClientImpl.cpp changes, but the rest of the changes LGTM.

I don't think this is the right layer to fix this issue. We probably want to change the behavior based on preference inside Selection::modify.

that probably needs to add this flag into WebCore::Settings.

Please make this an inline helper function.
