All right, some more progress for on-surface drawing.

Now if you draw a planar object (like rectangle, circle, polygon) in the 3D view and you snap 2 points on to a common plane, it will draw the object on that plane.

So this allows for stuff like this for example:


That's just moving the mouse over different faces to draw on different planes.

There are quite a few changes to help enable this kind of direct surface drawing, still working on a few more related things though.
