_height property fetching is probably not the only use for it, anyway
that's one use for sure. Note that it is not yet clear wheter the height
should be returned in local or global coordinate space.
Some implementation of get_height/width use get_matrix() while someother
use get_world_matrix(). I think we should definitely clean this up
starting from a clear doxygen comment about what's expected by them.
