spPaint3d is an object placement tool, very similar to geometryPaint from Maya. At this time, this is not a "scatter" tool as it does not contain any flood-like feature. It is entirely raycast based, so it doesn't expect any UVs from the target surfaces in order to properly place object. However, it doesn't allow for any kind of follicle-like functionality.
Very basic tweaks in the code to make it cross compatible with Python 2.x and 3.x Late is better than never... even when almost 15 years later :D
