D4947: [KTextEditor] Expose additional internal View's functionality to the public API

[Dominik Haumann]

  Reading this API, I still have some general thoughts:
  This is the first time we expose the concept of "visible lines". So far, this only exists internally in katetextfolding.h/cpp. By itself, this is fine, but given we do not expose folding information so far, I think the API is not complete.
  If we already provide infos about visible first / last visible line in a view, the complete API should also contain functions like isLineVisible(int line). But here, we have a problem, since the fistVisibleLine() and lastVisibleLine() are not the text folding lines, instead, its the visually visible drawn line on screen. Here, the term "visible" is used in two different contexts: once for screen visibility, and once for folding information. Internally, KTextEditor uses terms viewLine or displayedLine for this. Maybe displayedLine is the best here?
  
  Any comments? Are we lacking more API to make it feel complete?
