That's a good point. I should have used only 1 byte for it and not a 
whole integer.
Surely, using the gflags would work, too. But because of the fact that 
these bits do not only regard planes but are attributes of dxGeoms in 
general, wouldn't that be a misuse of such flags? I mean, shouldn't 
these bits used for properties of dxGeoms only?
Besides, either you accept that the same flags have different meanings 
in different geom classes, or if you assign them exclusively, you may 
eventually run out of bits.
