Hi there,

I am extending libpfiv with support for Inventor's text nodes.
Now, inventor can do 2 types of text:

SoText3: Object-space 3D text (scales like any 3d obj)
SoText2: Screen-space 2D text (fixed size, regardless of Z-depth)
(Note: the font itself is screenspace, but the text pos is still
properly treated as a 3D pos).

Now, SoText3 maps gently onto pfText,pfString
But how to handle SoText2?

pfSprite sounds promising, however, it is not a sprite, it's more
like a billboard, so of no use for SoTex2 nodes.

More info on SoText2 is here:

Any hints?
