I tried removing the 2D constraint from graphics.h.in.

4290         position.add_constraint (dim_vector (1, 2));

The result is an error occurs when the text position property is set using a 
1x2 value.

For compatibility we need to be able to set the text position using 1x2 or 1x3. 
When setting 1x2 the 3rd element should take on the default.

Is there a way to do that in graphics.h.in or should a custom inline definition 
for set_position be added for text objects?
