 == To do
 
+=== (Re-)create source files
+
+Since we don't have the sources, creating new cursors or modifying them is not
+gonna be easy. Possible solutions are to (semi-automatically?) create SVGs from
+the X11 cursors, start from scratch, or work directly with the X11 cursors.
+Ideas are welcome.
+
+=== Missing cursors
