-// The RenderThread class represents a background thread where RenderView
-// instances live.  The RenderThread supports an API that is used by its
-// consumer to talk indirectly to the RenderViews and supporting objects.
-// Likewise, it provides an API for the RenderViews to talk back to the main
-// process (i.e., their corresponding TabContents).
-//
-// Most of the communication occurs in the form of IPC messages.  They are
-// routed to the RenderThread according to the routing IDs of the messages.
-// The routing IDs correspond to RenderView instances.
