[Webkit-unassigned] [Bug 105023] Web Inspector: Change the InspectorOverlay to use native rather than canvas

--- Comment #4 from Brian Burg <burg at cs.washington.edu> ---
As a halfway option, I think we should make paint flashing always use a native backend directly (iOS uses CALayers, I think).

For inspecting nodes and interacting with the DOM tree, I think we still want canvas and JS running in the overlay page. The engineering effort required to implement and maintain the highlight rendering code in C++ is not worth it, IMO.

If a user simply wants to follow a rapidly-changing element on the screen, we can use a native code path to draw only a quad for it rather than the full highlight information (which is a substantial amount of data).
