+[x] Port font system from C to C3 (rewrite1)
 [ ] Update ARCHITECTURE.md
 [ ] Write a README.md
 [ ] Use an arena allocator for cache
 [ ] Do not redraw if there was no update (no layout and no draw)
 [ ] Better handling of the active and focused widgets, try
-    to maintain focus until mouse release (fix scroll bars)
