I would think not. An object that isn't drawn doesn't have any context
in world space (as defined by IDLgrView).

Why don't you:

A) draw it to an IDLgrBuffer
B) draw it to IDLgrWindow, then get the size and do whatever you are
doing with it, then draw again.

You could possibly calculate dimensions manually but that would depend
on you getting the view transform and the local coordinates of the
IDLgrText object. The first is doable but I doubt you can get at the
latter.
