* Removed unnecessary code and simplified some places in the drawing code paths.

* Calling BTextView::SetText() will invoke Window()->UpdateIfNeeded(), maybe
  since some recent changes only - we should perhaps look into this... (zooey),
  but the problem was that we called BControl::SetValueNoUpdate() after that,
  and thus we were drawing the color mark at the old offset and the invalidation
  in SetValue() was rendered effectless. Fixes #3719.
