- text and svg renderers should have a common interface
- text-buffer
- more efficient representation
- implement setter function e.g. no more (setf (aref text-buffer …) …)
- cell-colors in SVG renderer
- SVG images are bloated, due to overlapping lines
- what should be done with DISTANCE-FUNCTION etc?
- more algos (wilson’s algorithm for spanning trees, recursive backtracking)
