  I completely agree!  Besides:

	1. Not that many apps need 3D anyway;

	2. (like Jean Br�ort says) OpenGL is not printable, and IMHO all
applications should have a print option for any useful data they
produce. (by print I mean either on paper or to PDF file).  Let's face
it: in the real world, most apps are not that useful without print or
export options; it's like an editor that can open and edit files, but
not save them!

	3. All 3D is actually translated to 2D anyway, sooner or later, so a
determined programmer could do 3D anyway on top of 2D Cairo, albeit
requiring some 3D and math knowledge and not as much hw accelerated as
OpenGL.

  Regards.
