Hi Brent,

We just discussed this here... that would be nice, but a bit expensive 
to do on the fly as you would need to perform all collision detection 
(across all layers with labels) before rendering the contour lines, 
likely requiring multiple passes on the data. We got answers around the 
table ranging from "just use an opaque BG color for the label 
(geomtransform labelpoly)" to "anything is possible given enough time 
and money".  :-)
