this isn't the right order to put this message (ViewHostMsgs belong in the same
block, this is for browser->renderer messages)

Done.

+// next call to ViewMsg_GetFindMatchRects.

+// |rects| will either contain a list of the enclosing rects of all matches

+// greater than the |current_version| passed to ViewMsg_GetFindMatchRects (hence
