         - Move multiple points
     - Customizable background
         - Color, textures, procedural
-    - Further optimization
-        - Draw LOD size histogram for various cases (maybe we see that in our worst case 90% of strokes are down to 3-4 points)
-        - If we see lots of very low detail strokes, precompute zoom level for 3,4,... points left
 
 Bonus-bonus:
     - Actually infinite canvas (replace floats with something, some kind of fixed point scheme? chunks? multilevel scheme?)
