I tried it and it might be feasible (see the proof-of-concept in Gwyddion 2.21.20101106 or later snapshot). It does not fit entirely into the mode scheme: adding and removal make sense, setting probably, intersecting does not. At present only adding (drawing) and removal (erasing) works, everything else draws too. You have to draw slowly as it does not try to interpolate between the individual mouse positions so, drawing fast you get a sequence of points instead of a solid line (as you did in drawing programs in the 80s). Not sure if this worths implementing properly. At present the brush radius is not controllable but this I can improve easily.
