Bug 112172 – Web Inspector: do not aggregate non-main thread timeline events, handle them a generic fashion

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Andrey Kosyakov]

This removes the logic to aggregate rasterize events in timeline agent and instead sends them, along with potential nested events, to front-end, similar to how main thread events are handled. These are later supposed to be collated with front-end event collation logic from bug 112168.

Looks like rasterizeStartStackLevel could be a boolean (isInRasterize).

This is written as intended (though may be the method name is unfortunate), not having the top event is considered ok for the purpose of validation -- we hit this case if we started recording in the middle of the event.

Fair, this is atavism of an earlier implementation. Fixed.
