I want to use the outlines of a picture to define the parameters of a
button.  In other words, if someone clicks anywhere within the outlines
of a picture (no matter what shape the picture is), the button will be
activated.  I've been trying to improvise by filling all the nooks and
crannies of the pictures with tiny buttons, but, needless to say, this
is not an acceptable solution.

I don't know any languages but Hypertalk, but I'm told that making an
irregularly shaped picture "hot" is no sweat in a language such as C. 
Are there any Xcmd's that I could plug into Hypercard to do what I want
to do?  (I'm also told that Supercard is capable of doing this, but that
HC 2.0 will not have this capability.  Sure would be a nice addition, as
long as we're already taking suggestions, for v2.1.)

Any suggestions would be greatly appreciated.
