I had this same thought, but it was pointed out to me that starting with
1.2, and documented in the 1.2 enhancer docs (though I dont have em here),
there is supposed to be something extra attached to a gadget structure
that is the equivalent of the object collision mask in Bobs.  In other
words, since 1.2, masked gadgets HAVE been available.  I have not tried
it, nor have I actually looked at the documentation, but I have seen this
facility used in an actual product, on a map of Italy, "to boot". (grin)

Look it up, perhaps in intuition/intuition.h under the Gadget structure
description, or find the 1.2 enhancer docs.  "They" tell me it is
there.  (There's that wonderful "they" again).
