Text space

==========

Main changes:
- lines could be partially shown when they starts somewhere behind the upper
  boundary of area but because of word-wrapping some part of line will be show
- fixed caret navigatiog in area when tabs aren't replaced by spaces
- highlight the whole current line not only it's wrapped segment with caret
- when you're in replace mode cursor would be as long as the tab's width if it's under tab symbol

This fixes:
  #22399: Text Editor: word-wrapped lines prevent navigating through text with up-arrow.
  #21163: Text editor scrollbar problem with word wrap
