Polygon Buffer Query

[Abe Gillespie]

Is there a way to do this?  queryByPoint has the ability to supply a
radius but queryByShape does.  I thought that setting the layer's
TOLERANCE and TOLERANCEUNITS would help, but it doesn't seem to.  If
this isn't built in functionality, could anyone point me to an
algorithm that I can use to manually buffer a polygon before I supply
it to queryByShape?

Thanks.
