Maxime Coste 57c2b32d20 Introduce highlighting phases and display setup computation
Highlighters now run in 3 phases:
Wrap, Move, and Colorize. That way we guarantee the wrap
highlighter runs first, then eventual line numbers/flags,
and finally the colorizers.

We also run a `compute_display_setup` method thats responsible
for computing the lines that will be displayed, eventually
scrolling the view to ensure the cursor is visible.
