[Bf-funboard] UV space constraint (stick on surface)

[Hadrien Brissaud]

Paweł it works alright with single fixed objects; however this parenting
unlike a constraint is a fixed thing, so the object will always move along
with its parent vertex... even when a bone childof-constrains it on top (=
when you need to detach the object, you can't).
Furthermore it is impossible to make it part of an armature, for no more
than a single bone can be parented to a vertex (or a set of three
vertices). That means no pose mode for animating the object itself, and it
can't be part of the same action as the armature (granted this is not so
important).
